Question

Two supplementary angles have the same measurements of 2x - 8 and 8x - 12. What is the measurement of the largest angle?

Answer 1

Supplementary angles add up to 180 degrees.
2x - 8 + 8x - 12 = 180
10x - 20 = 180
10x = 200
x = 20

Angle 1 = 32
Angle 2 = 148
The measure of the largest angle is 148

Hope this helps =)
