For each side, you are given the points at the two ends.You need to find the distance between those two points.
Once you have all thee distances, add them up.
That's how.
Step-by-step explanation:
measure of exterior angle = sum of 2 non adjacent angles
4X = 90 + X
3X = go
X=30
exterior angle = 30x 4 =120
Either 4 times negative 20 and 4 times positive 5 x so....20x-16 orrrr 20x-80 (hope one of these help)
