Question

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

Answer 1

Answer:

Step-by-step explanation:

Let smaller angle be x and larger angle be x+18

Now x+x+18=180(supplementary angles sum up to 180)

2x+18=180

2x=180-18

2x=162

X=162/2

X=81

Larger angle is 81+18=99

Hope this helps

Answer 2

Answer:

Step-by-step explanation:

Let the smaller angle be x,

Then the largest angle is x+18,

x+x+18=90

2x+18=90

2x=90-18

2x=72

x=72/2

x=36

Therefore,

The smaller angle be x,

=36 degree

Then the largest angle is x+18,

=(36 +18)degree

=54 degree
