Answer:

F(30) = 1.8(30) + 32 = 86

F(C) = 10

10 = 1.8C + 32

-22 = 1.8 C

C = 12.222222222... or 110/9

The polygon is concave because if you placed lines directly on top of every side of the polygon, one or more of the lines would intersect an existing side. In a convex polygon, if you placed lines on top of the sides they wouldn't intersect another side.

So your answer is B) Concave.
