Question

9. The difference between two angles is 20°. If these
angles are complementary, find the angles.​

Answer 1

THEREFORE

the sum of two complementary angles=90°

given difference between 2 numbers=20°

let the first number=X

let the other number=2x

x+2x+20=90°

x+2x=90-20=70

then x=70

2×x=2×70=140

hence they are not complementary angles=140+70=210
