Question

An angle is 20 degrees less than it complement.find the angle

Answer 1

160 bro as we all know that a complement angle is of 180 degree hence we subtract 20 from it than 160 will remain. that's it

180 degree - 20 degree= 160 degree

Answer 2

Let the first angle be x.
Then, the second angle will be x - 20.

Given that,
=> x + (x - 20) = 90
=> x + x - 20 = 90
=> 2x = 90 + 20
=> 2x = 110
=> x = 110/2
=> x = 55°

Thus, the second angle will be x - 20 = 55 - 20 = 35°
