Please help me please please please
Step-by-step explanation:
Given :-A triangle have two angles that measures 85° and 23°.To Find :-Measure of the third angle.Solution :-Let the measure of the third angle of the triangle be x.
As we know that,
The sum of all three sides of a triangle is 180° which is the angle sum property of triangle.Therefore,
[tex] \sf \longrightarrow {\angle{A}\ +\ \angle{B}\ +\ \angle{C}\ =\ 180^{\circ}} [/tex]
[tex] \sf \longrightarrow {85^{\circ}\ +\ 23^{\circ}\ +\ x\ =\ 180^{\circ}} [/tex]
[tex] \sf \longrightarrow {108^{\circ}\ +\ x\ =\ 180^{\circ}} [/tex]
[tex] \sf \longrightarrow {x\ =\ 180^{\circ}\ -\ 108^{\circ}} [/tex]
[tex] \bf \longrightarrow {\underline{x\ =\ 72^{\circ}}}\ \bigstar [/tex]
∴ Hence, the measure of the third angle of the triangle is 72°.

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Let 'x' represent the number of yards of silk and 'y' represent the number of yards of cotton.
Here is a system of equations that represent the constraints in the situation.
x+y=4.25
16.90x+4y=36.35
Find the solution to the system of equations. You may use any method you want, but you must explain your reasoning and methods fully.
Answer:
Step-by-step explanation:
The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.
The two equations are known as simultaneous equation. They would be solved using elimination method.
x + y = 4.25 equation 1
16.90x + 4y = 36.25 equation 2
where:
x = yards of silk bought
y = yards of cotton bought
In order to determine the value of x, multiply equation 1 by 4.
4x + 4y = 17 equation 3
Subtract equation 3 from 2
19.25 = 12.90x
Divide both sides of the equation by 12.90
x = 1.49 yards
In order to determine the value of y, substitute for x in equation 1
1.49 + y = 4.25
y = 4.25 - 1.49
y = 2.76 yards
Answer:

HELP MEEEEE IM DESPERATE 30 POINTS!!!!!!
find x
Answer:
D
Step-by-step explanation:
the measure of a secant- tangent angle is half the difference of the intercepted arcs, then
[tex]\frac{1}{2}[/tex] (154 - (12x + 2) ) = 6x + 4 ( multiply both sides by 2 to clear the fraction )
154 - 12x - 2 = 12x + 8 , that is
152 - 12x = 12x + 8 ( subtract 12x from both sides )
152 - 24x = 8 ( subtract 152 from both sides )
- 24x = - 144 ( divide both sides by - 24 )

y = x2 + 3x + 2
x + y = 2
y = x2 − 3x + 2
x − y = 2
y = x2 − 3x + 2
x − y = 3
y = x2 − 3x + 2
x + y = 3
The solutions of the given equations are given by equating the
variables to gives;
First part; 4.00 secondsSecond part; (0, -6) and (1, -5)Third part; (4, 11) and (0, 7)Fourth part: y = x² + 3·x + 2; x + y = 2How can the (common) solution be found?First part;
The given functions are;
y = -3·x² + 24·x + 3, and y = -4·x² + 25·x + 15
When the balloons collided, we have;
The height are equal, which gives;
y = y
-3·x² + 24·x + 3 = -4·x² + 25·x + 15
-3·x² + 24·x + 3 - (-4·x² + 25·x + 15) = x² - x - 12 = 0
Which gives;
x² - x - 12 = (x - 4) × (x + 3) = 0
x = 4, and x = -3
The time at which the balloon collide at the highest point is therefore;
At the time, x = 4.00 secondsSecond part;
The given system of equations are;
x - y = 6
y = x² - 6
y = x - 6
Which gives;
x - 6 = x² - 6
x = x²
Which gives;
x = 0 or x = 1
Similarly, we have;
x = y + 6
Which gives;
y = (y + 6)² - 6
y² + 11·y + 30 = 0
(y + 5)·(y + 6) = 0
Which gives;
y = -5, or y = -6
When y = -5, we have; x = -5 + 6 = 1
The solution are therefore;
(0, -6) and (1, -5)Third part;
The equations are; y = x + 7 and y = x² - 3·x + 7
At the solution, the u-values are equal, which gives;
y = y
x + 7 = x² - 3·x + 7
x² - 3·x + 7 - (x + 7) = 0
x² - 4·x = 0
x·(x - 4) = 0
x = 4, or x = 0
When x = 4, y = 4 + 7 = 11
When x = 0, y = 0 + 7 = 7
The solutions are located at points;
(4, 11) and (0, 7)Fourth part;
Given that the point of intersection of the line and the quadratic function
is the point (2, 0), we have;
On the linear function, when y = 0, x = 2
The possible linear function functions is therefore;
x + y = 2
From the quadratic function that accompanies the above linear function, we have;
y = x² + 3·x + 2
When x = 0, y = 0² + 3×0 + 2 = 2
Therefore;
The correct option is; y = x² + 3·x + 2, and x + y = 2Learn more about the solutions of equations here:

A graph is a way to represent a lot of data in a visual format. The shape of this graph is best described as skewed.
What is a graph?A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
here, we have,
A.) A symmetric graph is a graph in which the left half of the graph looks like the mirror image of the right half of the graph. Since the graph has no symmetry it is not a symmetric graph.
B.) Skewness is a distortion or asymmetry in a set of data that deviates from the symmetrical bell curve, or normal distribution. The curve is said to be skewed if it is displaced to the left or right. As we can see that the shape of the graph is the left tilted bell shape.
C.) A constant graph is a graph in which the value of each bar lies on the same horizontal value. Since the shape of the graph is not a horizontal line, it is not a constant shape graph.
D.) When a graph has Peak and Valleys in a graph, the values of the graph are different from each other, therefore, forming peaks and valleys in a graph, which looks like a spline. Since the value of the graph is decreasing towards the right side of the graph. Therefore, the graph of the shape is not of a peak and valley.
Thus, the shape of this graph is best described as skewed.

• She has 2 pairs of black pants, 1 pair of brown pants, and 2 pairs of blue pants in her
closet
. She also has 2 pink T-shirts and blue T-shirts in her closet.
• Without looking, Jonny pulls out one pair of pants and one T-shirt from her closet.
What is the probability that Jenny pulls out a pair of black pants and a blue T-shirt?
Answer:
[tex]\huge\boxed{\bf\: Probability = \frac{4}{9}}[/tex]
Step-by-step explanation:
According to the given information,
Pairs of black pants = 2Pair of brown pants = 1Pairs of blue pants = 2Then, total pairs of pants = 2 + 1 + 2 = 5
Similarly,
Pink T-shirts = 2Blue T-shirts = 2Then, total number of T-shirts = 4
This gives us the total nunber of clothing articles with Jenny, i.e.,
Total pairs of pants + Total number of T-shirts
= 5 + 4
= 9
Now, the probability of pulling out a pair of black pants & a blue T-shirt will be:
Total pairs of black pants + Total nunber of blue T-shirts/Total clothing articles
= 2 + 2 / 9
= 4/9
