The sum is 90 degrees then the angles are complementary angles. The value of x will be 35 degrees.
<h3>What is an angle?</h3>
The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
We have
x + x - 20 = 90
2x = 70
x = 35
Then the value of x will be 35°.
