Question

find the angle which is equal to twice of its complement.
​

Answer 1

Answer:

Step-by-step explanation:

let the angle be x

complement angel is 90-x

x = 2(90-x)

x = 180 - 2x

3x = 180

x = 60

60 is twice its complement which is 30 degrees. you could have thought of this mentally as well if algebraically it doesn't make sense.  

Answer 2

Step-by-step explanation:

If an angle is twice its complement you can represent the angle as x and other as 2x . since they are complement , there sum is 90 degrees . this means that one angle is 30 deg. the angle that is twice that value is 60 degrees.
