Question

. If y⁰ and ( y+20)⁰ are compliments of each other, find the value of y. *

Answer 1

Answer:

y = 35, (y+20) = 55.

Step-by-step explanation:

y + (y+20) = 90 (Complimentary Angles sum up to 90 degrees.)

y + y + 20 = 90

2y + 20 = 90

2y = 90 - 20 (bringing non variable terms on the right side)

2y = 70

y = 70/2

y = 35.

Verification:

y + y + 20 = 90

35 + 35 + 20 = 90

70 + 20 = 90

90 =  90

LHS = RHS

Hence, Verified.
