Answer:
y = 54
Step-by-step explanation:
We know the sum of the angles of a triangle are 180
72+y+y = 180
Combine like terms
72 + 2y = 180
Subtract 72 from each side
72-72 +2y = 180-72
2y = 108
Divide each side by 2
2y/2 = 108/2
y = 54
D is the answer because it says each and that’s a key word to understand that it’s multiplying
<span>A. The angles are neither complementary nor supplementary.
As their sum is neither equal to 90 nor 180, they are none of them
