A
D

Answers

Answer 1

Answer: ZA= 72 ZB=108

Explanation:

5y-3 = 3y + 27

2y-3=27

2y=30

y=15

(5(15)-3)

= 72= ZA

180-72= 108 = ZB

Answer 2

The measure of <A and the measure of <B given their equation is 72°

How to find angles

<A = (3y + 27)°

<B = (5y - 3)°

Equate both equations

3y + 27 = 5y - 3

collect like terms

3y - 5y = -3 - 27

-2y = -30

divide both sides by -2

y = 15

Therefore,

<A = (3y + 27)°

= 3×15 + 27

= 45 + 27

= 72°

<B = (5y - 3)

= 5×15 - 3

= 75 - 3

= 72°
