Question

Two angles are supplementary. The measure of one angle

is 16 more than two times the measure of the other
angle. How many degrees are in each angle?

Answer 1

82 and 98.

Explanation:

set up 2 equations

x+y=180

2x+16=180

you start by solving the second equation to find one of the angles.

180-16= 164

2x=164

164÷2= 82

x=82

since you've solved that equation, add in the missing variable to solve for the next one

82+y=180

180-82= 98
