Answer:
132
Step-by-step explanation:
Alternate angles are equal. Therefore, A = B.
<u>Find x</u>
5x - 18 = 3x +42
2x = 60
x = 30
<u>Substitute x in angle A</u>
5(30) - 18 = 132
Pe<u>rim</u>eter is the outside of a shape. If I'm right (which I'm usually not), you just want to add 27.71 to itself 6 times for this shape? Which would make 166.26.
The mean to this question is 87.875
