Answer:55 degrees

Step-by-step explanation: We are dealing with a right angle which is also the same as a complementary angle that adds up to 90 degrees.

The following equation can be obtained from the right angle

(x-20)+x=90

Simplifying like terms

2x-20=90

We want to solve for x this means we want to get x terms on its own.

We need for -20 to disappear the only way to do this is to add 20. What we do to one side we must do to the other.

2x-20+20=90+20

2x=110

To solve for x we need to divide both sides by 2

2x/2=110/2

x=55 degrees
