Question

The larger of the two supplementary angles exceeds the smaller by 18degree.what is the larger angle?

a.162°
b.100°
c.81°
d.99°​

Answer 1

Answer:

(d)99°

Step-by-step explanation:

Let the smaller angle be x°

So the larger angle=x+18

x+x+18=180

2x+18=180

2x=180-18

2x=162

x=162/2

x=81°

Smaller angle=x=81°

Larger angle=x+18=81+18=99°
