Question

a larger of 2 supplementary exceeds the smaller by 18 degrees. find them.

Answer 1

x + (x + 18)=90
2x + 18 = 90
2x = 90 - 18
2x = 72
x = 36

Answer 2

Step-by-step explanation:

HLW MATE HERE IS YOUR CORRECT ANSWER.......

Let the larger angle be 'x' and the smaller one be 'y'

ATQ,

x =y +18 ---------------------(1)

We know that, sum of supplementary angles =180°

x+y=180°---------------------(2)

SUBSTITUTE x=y+18 in eq (2)

y+18+y=180°

2y=180-18

2y=162

y=162/2

✓y=81

x=81+18

=99

THEREFORE,

THE ANGLES ARE 81 AND 99
