Question

25 points What is the measure of A? What is the measure of B?

Answer 1

<A = 72°

<B = 108°

Explanation :

<A = <C

(5y - 3)° = (3y + 27)°

5y-3y = 27 + 3

2y = 30

y = 15

<A = (5y - 3)°

<A = (5 x 15) - 3

<A = 75 - 3

<A = 72°

<B + <A = 180°

<B + 72° = 180°

<B = 180° - 72°

<B = 108°
