Question

the larger of two supplementary angle exceed the smaller by 18 degree find them by substitution method

Answer 1

let an angle be x

let the other be y

such that y=x+18

according to the equation

x + y=180

x + x + 18 =180

2x + 18 = 180

2x = 180 - 18

2x = 162

x = 81

hence y = x + 18

hence y = 81 + 18

hence y = 99
