Question

please tell me correct answer according to the question please​

Answer 1

Step-by-step explanation:

Complementary angles add up to 90 degree

Therefore ,

( y - 20 ) + ( y + 30 ) = 90

2y + 10 = 90

2y = 90 - 10

2y = 80

y = 40

When we substitute ,

( y - 20 ) = 20

( y + 30 ) = 70

Hope this helps
