22 & 23) x = 10 (solved for x in 5x+80=3x+100)
5x + 80 = 130 degrees (angle LMN)
3x + 100 = 130 degrees (angle PMQ)
130 * 2 = 260 degrees
360 - 260 = 100
100 / 2 = 50 degrees (angle LMP and angle NMQ)
24) 60 degrees and 30 degrees. 60 is twice as large as 30, and they bothd this add up to 90 degrees.
Complementary angles add up to 90 degrees *
