The angles of the triangle are ∠Q=59°, ∠R=90°,∠S=31°.
What is a triangle?
In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.
Based on the sides of a triangle, a triangle is classified into 3 types, namely:
Scalene Triangle – All the sides are of different measures.
Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.
Equilateral Triangle – All the 3 sides of a triangle are of the same measure.
Based on the angles of a triangle, a triangle is classified into 3 types, namely:
Acute Angle Triangle – All the angles of a triangle are less than 90°.
Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.
Right Angle Triangle – One of the angles of a triangle is equal to 90°.
Now,
As sum of all angles of triangles=180°
90+2x+33+5x-34=180
7x=90+1
x=13
Therefore,
∠Q=59°, ∠R=90°,∠S=31°

In triangle ABC. AD is a median. P and q are the midpoints of AB and AD respectively. If ar (ABC) = 72cm ^ 2 then ar (APQ) =?
Answers
The area of the ar (APQ) = 18 cm ^ 2 for the given triangle ABC.
Define the term median of triangle?A line segment from such a vertex here to middle of the other side is what is meant by a median. When the vertex is just an angle in a right triangle and the non-congruent angle about an isoceles triangle, it also functions as an angle bisector.Given that:
AD is ABC's median, ABC will be divided into two distinct triangles by AD.We are aware that a triangle's middle separates that into two triangles with equal areas. Triangle ABC's median is AD, and ABD's median is PQ.Then, area (ΔABD) = area (ΔADC)
And, area (ΔABD) = 1/2 area (ABC) eq.....(i)
Thus, In ΔABD, PQ is the median, as PQ are the mid points on AB and AD respectively.
Then,
ar (APQ) = 1/2 ar(ΔABD)
ar (APQ) = 1/2 × [1/2 ar(ABC)] ....... (Use eq (i))
ar (APQ) = 1/4 ar(ΔABC)
ar (APQ) = 1/4 *72 cm ^ 2

A company is offering a bank account. The value, in dollars, of the account, is represented by the function A(t)=50,000(1.02)^t, where t represents the number of years since the account was first opened. Determine the average rate of change of the account value from t = 0 to t = 5. Express your answer in the nearest cent. PLS HELP!!!
Answers
The average rate of change of the account value from t = 0 to t = 5 is the change in the account value divided by the change in time, or (A(5) - A(0))/(5 - 0).
We can substitute the given function into the equation:
A(t) = 50,000(1.02)^t
So,
A(5) = 50,000(1.02)^5
and
A(0) = 50,000(1.02)^0
Now we can substitute these values in the equation of average rate of change:
(A(5) - A(0))/(5 - 0) = (50000(1.02)^5 - 50000(1.02)^0) / (5-0)
This simplifies to
(50000(1.02)^5 - 50000) / 5
Which is approximately equal to 67,622.05
So the average rate of change of the account value from t = 0 to t = 5 is approximately 67,622.05.

The linear equations for the graph is obtained to be option D: y = x + 2 and y = -x - 4.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The graph of two lines are given.
For the first line going from top left corner to bottom right corner, the point of coordinates are (-5, 1) and (-3,-1).
The slope-intercept form of an equation/function is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
[-1 - 1]/[-3 - (-5)]
(-2)/(2)
-1
So, the slope point is obtained as m = -1.
The equation becomes - y =-x + b
To find the value of b substitute the values of x and y in the equation -
-1 = -(-3) + b
-1 = 3 + b
b = -1 - 3
b = -4
So, the value for b is -4.
Now, the equation becomes -
y = -x - 4
Now, for the second line going from bottom left corner to top right corner, the point of coordinates are (-1, 1) and (-3,-1).
The slope-intercept form of an equation/function is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
[-1 - 1]/[-3 - (-1)]
(-2)/(-2)
1
So, the slope point is obtained as m = 1.
The equation becomes - y = x + b
To find the value of b substitute the values of x and y in the equation -
-1 = (-3) + b
-1 = -3 + b
b = -1 + 3
b = 2
So, the value for b is 2.
Now, the equation becomes -
y = x + 2
Therefore, the two equations are y = -x - 4 and y = x + 2.

What is ratio ?
Ratio can be defined as the given value divided by the total value.
The easiest thing to do first is convert all of these fractions to common denominators, and figure out the rest of the problem from there.
So the common denominator between 1/3 and 1/4 is 12, so convert these to fractions to /12 and continue on.
Think of the whole book being 12/12, and Sarah read 4/12 of it in the morning, so we know she has 8/12 left of it. Since we know she still has 3/12 left to read by the end of the day, we can subtract 8/12 - 3/12 to find out how much she read at night, which is 5/12. This makes sense because when we add all the fractions up (4/12 + 3/12 + 5/12) it comes out to 12/12, which is the whole book.
Therefore, The Angel read 5/12 of the book at night if Angel read 1/3 of a book in the morning, and he read some more at night. By the end of the day, he still had 1/4 of the book left to read.

and Marilyn is 4 feet 8 inches tall.. What is the average height of these 4 friends? Explain
how you found your answer.
Answers
Answer:
the average height is 5 feet 0 inches
Step-by-step explanation:
To find the average height of Maria, Marla, Mandy and Marilyn, we need to add up their individual heights and divide by the number of people in the group.
First, we need to convert all the heights to a common unit of measurement. Since inches are the smallest unit of measurement, we will convert all the heights to inches.
Maria: 5 feet 3 inches = 63 inches
Marla: 4 feet 11 inches = 59 inches
Mandy: 5 feet 2 inches = 62 inches
Marilyn: 4 feet 8 inches = 56 inches
Now we can add up the heights:
63 inches + 59 inches + 62 inches + 56 inches = 240 inches
To find the average, we divide the total height by the number of people:
240 inches / 4 people = 60 inches
So the average height of these four friends is 60 inches or 5 feet, which is the same as 5 feet 0 inches.
Therefore, the average height of these four friends is 5 feet 0 inches.
the variable bwght gives the birthweight of the baby (in ounces). what is the difference in average birthweight between smoking mothers and non- smoking mothers?
Answers
The difference in average birthweight between smoking mothers and non- smoking mothers is, mothers who smoke cigarettes during pregnancy have, on average, lower birthweight children.
When cigs=0, the bwght is 119.77 ounces.
The average birth weight of the baby when the mother is not a smoker is 119.77 ounces.
When cigs=20,
bwght = 119.77 − 0.514(20) = 109.49,
The bwght is 109.49 ounces.
However, as more cigarettes are smoked, the birthweight of the baby decreases at the rate of 0.5138 ounce for every additional cigarette smoked per day.
Obviously, mothers who smoke cigarettes during pregnancy have, on average, lower birthweight children.
