Question

the larger of two supplementary angles exceeds the smaller by 18 degree .find them​

Answer 1

the the smaller angle be x, then greater one = x+18,

x+x+18=180(sum of 2 supplementary angles)

2x+18=180

2x=180-18

2x=162

x=162/2

x=81

the measure of greater one

81+18=99

Answer 2

my answer to this question is 99
