Answer:
x= 55
Explanation:
Since we know they are complementary, we know that their angles would add up to 90 degrees. Let's write an equation setting both angles equal to 90 and solving for x.
(x-20)+x=90
2x-20=90
2x=110
x = 55°
We know that a right angle has 90° so,
x + x - 20° =90°
2x - 20° = 90°
2x = 110°
