Question

if an angle differ from its complementary by 10 degree find the angle

Answer 1

let the first angle be x
therefore another angle is 90-x
Atp
x-(90-x)=10
x-90+x=10
2x=100
x=50°
another angle =40°

Answer 2

let the no. be x
(90-x )- x =10
90-2x =10
2x=90-10
2x=80
x=40
thus the angles are 50 and 40 degrees
