If △ABC is a right triangle, A = 37° and AB = 12, then find the lengths of B C and A C . Round your answers to the nearest integer
Answer:
BC= 9.04
AC= 15.0
mark brainliest
Answer:
BC ≈ 9
AC ≈ 15
Step-by-step explanation:
The side adjacent to the given angle is the one whose length is known, so the relevant trig relations are ...
Cos = Adjacent/Hypotenuse ⇒ cos(37°) = AB/AC
Tan = Opposite/Adjacent ⇒ tan(37°) = BC/AB
Then the unknown sides are ...
AC = AB/cos(37°) = 12/cos(37°) ≈ 15
BC = AB·tan(37°) = 12·tan(37°) ≈ 9
__
Additional comment
Rounded to the nearest degree, angles 37° and 53° are the acute angles found in a 3-4-5 right triangle. Since the given side is adjacent to the smallest acute angle (not the hypotenuse), it will correspond to "4" in the 3-4-5 triangle. That means the scale factor is 12/4 = 3, and the other two sides are 3·3 = 9 and 3·5 = 15.
The numbers work out this way only by rounding to tenths or integers.

Q5. The coordinates of A and B on a number line are -7 and 9. The coordinates
of C and D on a number line -4 and 12. Are AB and CD congruent? If yes, what
is the length of each segment?
Answer:
are congruentlength: 16 unitsStep-by-step explanation:
The length of a segment on a number line is the difference of its coordinates.
AB = 9 -(-7) = 16
CD = 12 -(-4) = 16
AB and CD both have a length of 16 units, so are congruent.

20 points!!!! Freya is collecting 50p and £1 coins. When she has 18 coins the value of them is £13.
Let x be the number of 50p coins and y the number of £1 coins. Write a pair of simultaneous equations for this.
Answer:
x + y = 180.5x +y = 13Step-by-step explanation:
The system of equations formalizes the given relationships regarding the number of coins and their value.
x + y = 18 . . . . . . Freya has 18 coins
0.50x +1.00y = 13 . . . . their value is £13

Answer:
ill try:
Learning about the connections between finding the GCF of numbers, the distributive property, multiplying polynomials, and factoring has helped me understand how to simplify and solve for equations. The distributive property taught me about how to easily simplifying equations, since the requirement is to just distribute the given to the number(s). Factoring has taught me how to make an equation easier to solve. For example, when I'm given a problem that has very large numbers, I can see if they have a GCF and this will help me solve the problem in no time!

Answer plspslspslspl.
Start with definition of absolute value, |x|.
It says, |x| = x, for any x >= 0 and
|x| = -x, for any x < 0
Now, instead of x, we have the expression x+120 inside the absolute value brackets:
|x+120|
Play the same game as above - what is the absolute value here?
|x+120| = x+120 for (x+120)>=0 and
|x+120| = -(x+120) for (x+120)<0
Now, recognize that the last condition (x+120)<0 is the same as writing x<-120. That is the condition in the question. Therefore the absolute value |x+120| will equal the second expression (for that condition), namely -(x+120), or -x-120.

Answer:
1. width = 4 inches length = 13 inches
2. 225 m²
Step-by-step explanation:
1. So we know there are two sides and one side is 9 more than the other.
We let one side be x as we don't know what the number is. The other side is x+9 as its 9 more than the first side but we don't what that is either.
We know the area of a rectangle is A = bh.
The two sides are x and x+9
so, x(x+9) = 52
x² + 9x = 52
x² + 9x - 52 = 0
x² + 13x - 4x - 52 = 0
x(x+13) -4(x+13) = 0
(x-4)(x+13) = 0
x = 4 x = 13
The answer is x = 4 because you can't have x = -13 as negative lengths don't exist.
So if one side is x and the other side is x+ 9. Then plugging in 4 to both gets us, 4 and 13 as the dimensions.
The length is 9 more than width so,
length = 13 inches and width = 4 inches.
2. We know the area of a rectangle is A = bh.
One side is x + 10 and the other is x+15
Area is 750.
(x+10)(x+15) = 750
x²+15x+10x+150 = 750
x²+15x+10x-600 = 0
x²+25x-600 = 0
(x+40)(x-15) = 0
x = 15 as we can't have x = -40 because negative distance does not exist.
The bistro has sides x and x.
So the area is x * x.
15 * 15 = 225 m².

Answer:
25 miles, and the cost will be $37.50.
Step-by-step explanation:
Mose's charge can be represented by f(x) = 0.5x + 25, Holly's charge can be represented by g(x) = 0.3x + 30.
Set the equations equal to each other: 0.5x + 25 = 0.3x + 30.
0.2x = 5
x = 25
Substitute 25 for x: f(x) = 0.5(25) + 25 = 37.5, g(x) = 0.3(25) + 30 = 37.5.
So f(x) = g(x) at x = 25, and the output will be 37.5.
