Question

the larger of two suplimentary angle is exeed the smaller by 18 degree. find the two angle.

Answer 1

let the smaller angle be X and as the greater angle exceeds the smaller one by 18 degree so the larger angle is X +18

as these are supplementay angles their sum is equal to 180 degree

X+X+18=180

2X=180-18

2 X=162

X=81

smaller angle is 81 degree an larger angle is X +18=99

thus angles are 81 and 99 degree
