Answer 2

Given:

We have given Two angles whose sum is  90° .

To Find:

We have to find what these angles are called?

Step-by-step explanation:

• Let the one angle be x and the other angles be y.
• We have given the sum of these angles is 90°.

        $x+y=90^\circ$

• These are the angles which are commonly known as COMPLEMENTARY ANGLES.
• Complementary angle:
• Because the three angles of a triangle sum up to 180 degrees, and the right angle has already taken 90 degrees, the two non-right angles in a right angled triangle are complimentary. When two angles total up to 90 degrees, we call them "Complementary." since a complete angle is thought of as a right angle.
