when you simplify this you get 1/16x^8
Subtract the one value from 180 and then divide that number by 2 to get the 2 values. So if one side is 90, they other sides would be 45 each
109 degrees and the missing angle are supplementary angles, so they add up to 180 degrees.
180 - 109 = 71
The measurement of ULE can now be found since we now have 2 angles with their degrees. So we add those angles together...
71 + 49 = 120
Now we subtract that from 180 (all of the angles add up to 180 in a triangle) to get the m180 - 120 = 60
The m
