Question

Find the complement of the angle (10+y)∘.

Answer 1

complement angles = 90°



therefore

$10 + y = 90 \\ \\ y = 90 - 10 \\ \\ y = 80$


hence the other angle
e.i., is 80°

Answer 2

Hello Dear!!!

Here's your answer...

Given,

Angle is 10+y

Sum of complementary angles is 90

Then

Other angle is

90-(10+y)

90-10-y

80-y

Complementary angle is 80-y
