Question

the larger of two supplementary angle exceeds the smaller by 18 degree find its radius? ?

Answer 1

hi...its an easy question ...
Let first angle = x
And second number = y
As both angles are supplementary so that sum will 180
x + y = 180
x = 180 - y ... (1)
Difference is 18 degree so that
x – y = 18
Plug the value of x we get
180– y – y = 18
- 2 y = -162
y = -162/-2
y = 81
Plug the value back in equation first we get
x = 180 – 81 = 99

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
