Question

The measure of an angle is twice the measure of its supplement.


how many angles are there? What is their relationship?
How can you use algebra, such as using the variable x, to help you?

Answer 1

supplementary angles add up to 180 degrees
if angle is x what is the formula for its supplement?

Answer 2

x + 2x = 180?

Answer 3

supplement of x = 180-x
x is twice that so:
x = 2(180 - x)
solve this to find x
