Question

If an angle differs from its complement by 10°, find the angle.

Answer 1

Answer:

x+y=90

x-y=10

2y=80

y=40

x=50

Answer 2

Answer:

let the angles be x and y

as we know x+y = 90° ( complimentary angles)

and the given difference between them is 10°

so, x-y = 10°

x = 10° +y

: 10°+ y + y = 90°

2y = 80°

y= 40° ; x = 10° + 40° = 50°
