Question

the larger of two supplementary exceeds the smaller by ${18}^{o}$ find them ​

Answer 1

Let, Bigger angle=x

smaller angle=y

A.T.Q.

x=y+18---------1

x+y=180---------2

Substituting the x=y+18 in equation 2

(y+18)+y=180

2y+18=180

2y=180-18

y=162/2

y=81 degree

x=y+18

=81+18

=99 degree
