A=5x-12. B=2x+24. Solve for x and then find the measure of angle measure B

Answer:
x = 12°
<B = 48°
Step-by-step explanation:
As alternate angles are equal,
< A = < B
Given that,
< A = 5x - 12
<B = 2x + 24
So,
5x - 12 = 2x + 24
Now solve for x.
5x - 2x - 12 = 24
3x - 12 = 24
3x = 24 + 12
3x = 36
Divide both sides by 3.
x = 12°
Now let us find the measure of angle B.
< B = 2x + 24
< B = 2 × 12 + 24
< B = 24 + 24
<B = 48°
