Question

If an angle is 28° less than its complement . Find the angle

Answer 1

Assume the angle that you want to find out = x

Then its complement = 90° - x

Therefore, from the given statement, x = 90° - x - 28  

This in turn implies that 2x = 90-28 = 62

Thus, the desired angle x = 31°

Answer 2

let the angle be x 

its complement  be (90 - x) 
 
ATQ 

x = 90 - x - 28 

2x = 62 

x = 31
