Question

The larger of two supplementary angles exceeds the smaller by 20 degree . find them.

Answer 1

Answer:

80° and 100°

Step-by-step explanation:

sum of supplementary angles= 180°

let the smaller angle be x

larger angle = x+20

$x + x + 20 = 180 \\ \\ 2x = 180 - 20 \\ 2x = 160 \\ x = 160 \div 2 \\ x = 80$

smaller angle = 80°

larger angle = 80+20 = 100°
