Question

Turns out math isn't so bad!

Answer 1

1. It has five angles, so that means it's a pentagon.
2. All of the angles are less than 180, so it is concave.

Answer 2

I mean convex, not concave.

Answer 3

You have five interior angles, so you're going to have a pentagon of some type. The interior angles for a pentagon, if convex, will add to 540 (because you can divide the pentagon into 3 triangles, each of which total to 180 degrees). A convex polygon will contain all diagonals from each vertex. Like so:

Answer 4

160 + 160 + 70 + 75 + 75 = 540 btw, substitute one of the 70 degree angles in my drawing for another 75.

Answer 5

All good now, @victoria650 ?

Answer 6

btw, a concave pentagon, which is different from what your answer is, would look like:

Answer 7

uw!

Answer 8

Good luck in all of your studies and thanks for the recognition! @victoria650
