Answer:
multiply 22.8 by 22.8
Step-by-step explanation:
Complementary is which add up to 90 °
8)
59+31=90° complementary angles.
supplementary is which add up to 180°
10) 156+24=18 supplementary angles
12)
shows right angle=3x+45=90
3x=45
x=15°
14) supplementary angles
2x+3x+25=180
5x+25=180
x=31°
16) again it makes supplementary angles
x+2x+21=180
3x+21=180
x+7=60
x=53°
