Question

( y – 40 )° and ( y + 30 )° are the measure of complementary angles . Find the measure of each angle . answer fast urgent​

Answer 1

Answer:

Sum of all complementary angles equals 90°.

Steps to solve the sum

y - 20 + y + 30 = 90°

2y + 10 = 90°

2y = 90° - 10

2y = 80°

=> y = 80 / 2 = 40°

Hence the two angles are :

( y - 20 ) = 40 - 20 = 20°

( y + 30 ) = 40 + 30 = 70°

Angles are 20° and 70°.
