Question

The measure of an angle is one third the measure of its supplement. What is the measure of the angle?

Answer 1

If we have an angle, let's say A, how would you express its supplement?

Answer 2

Would you just divide the angle by 1/3 @bibby

Answer 3

Hint:sum of supplementry Angles is 180°

Answer 4

if we call the supplementary angle B, we have A+B=180

Answer 5

But how do you figure out what A is? @bibby

Answer 6

Now you can do B=1/3(A)

Answer 7

Then plug this value of B in
A+B=180°
And you get equation in single variable AA so you can find it easily

Answer 8

In variable A

Answer 9

@kenna_098 is this helping you

Answer 10

I'm still really confused @Pawanyadav

Answer 11

A+B=180 and B=A/3
So A+A/3=180

Answer 12

Can you find A now

Answer 13

sum of these 2 angles = 180 (because they are 'supplementary')
