Question

The measure of angle one is five less than four times the measure of angle 2. if angle 1 and angle 2 from a linear pair, what are their measures?

Answer 1

Linear pairs add up to 180 degrees.

x=4y-5
x+y=180

Substitute x
4y-5+y=180
5y-5=180
5y=185
y=37

Plug the y value in
x+37=180
x=143

Final answer: angle 1= 143 degrees, angle 2= 37 degrees
