Let mA = 40°. If B is a complement of A, and C is a supplement of B, find these measures. mB = ° mC = °

Nesterboy [21]

If the measure of angle A = 40 and B is a complement of A, then the measure of angle B = 50. If C is a supplement of B, then the measure of angle C = 130.

the measure of angle A = 40
the measure of angle B = 50
the measure of angle C = 130

Hope this helps!

Answer:

Part A: D. $y = (x + 1)(x+3)\\$

Part B: C. $3x(x-3) = 0\\$

Step-by-step explanation:

For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.

The equation: $y = (x + 1)(x+3)$

Now plug in 0 for x.

$y = (0 + 1)(0+3)\\$

Now solve.

y = (1)(3)

y = 3

This proves that this is the correct answer.

For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.

The equation: $3x(x-3) = 0$
