Question

The larger of two supplementary angles exeeds the smaller by 18 dgrees.find them

Answer 1

let the smaller angle be x then larger one is x+18

sum of supplementary angles=180

x+x+18=180
2x=180-18=162
x= 162/2=81
larger angle = 81+18=99


so the angles are 81 and 99...

Answer 2

Let the larger angle be X and smaller beY
Than
ATQ
X- y= 18
And
We know
X+y =180
Now add eq1and 2 we get
2X=198
X=99
So Y =180- 99
Y = 81
