What is the degree measure of an angle whose measure is double the measure of its complement?

x + 2x = 90

3x = 90

x = 30

 

The angle is 60

complement = the angle that added with the original angle forms a right angle

 

Let the angle measure be x.

 

x = 2(90 - x)

x = 180 - 2x

3x = 180

 

x = 60 degrees.
