=-12.166/-1.54 [if - is in both numerator and denominator then they are cancled out]
=12.166/1.54
=7.9
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Let x represent the smaller angle:
x + (x + 81.2) = 180
2x + 81.2 = 180
2x = 98.8
x = 49.4 degrees
therefore:
smaller angle = 49.4 degrees
larger angle = 49.4 + 81.2
= 130.86 degrees
