Question

If the complement of an angle is 40 less than its supplement, find the angle.

Answer 1

The 2 angles in a complement would be (in degrees) 65 and 25

Answer 2

Complement = Supplement - 40 degrees

Then 

     90 - x        =  180 - x        - 40 (degrees)

Unfortunately, " -x " cancels here, and we are left with 90 = 180 - 40.  This is never true.  Please ensure that you have copied the origianl problem down correctly.
