How many sides is that? I can't tell for sure.  It looks like 10.

your guess is as good as mine

tacobell518 · Answer

yeah its 10

retireed · Answer

Okay I'll say 10.

First you need to determine the what one exterior angle is, since the SUM of ALL of the exterior angles is the same for every figure.

Once you know what one exterior angle is.  You can calculate the interior angle and then multiply by the number of interior angles.

This is very high level and hard to follow, I know.  But read it and let it soak in for a second and then ask any questions you have.
