What is the measure of ZA?
B
С
(3y + 27)°
What is the measure of ZB?
(5y - 3)
A
D
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
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 equations3y + 27 = 5y - 3
collect like terms3y - 5y = -3 - 27
-2y = -30
divide both sides by -2y = 15
Therefore,
<A = (3y + 27)°
= 3×15 + 27
= 45 + 27
= 72°
<B = (5y - 3)
= 5×15 - 3
= 75 - 3
= 72°
