Question

The larger out of two supplementary angles exceeds the smaller by 18⁰. The angles are:
​

Answer 1

Answer:

y=81;x=99

Step-by-step explanation:

Let the angles be x and y

So, x+y=180

x=y+18

⇒y+18+y=180

∴y=81;x=99

Answer 2

Answer:

x+y=180⁰

x=y+18

y+y+18=180⁰

2y=162⁰

y=81⁰

x=81+18=99⁰
