Question

Doing test corrections and still have no clue what to do

Answer 1

the answer would be 30 sides

Answer 2

Exterior angle = 180- Interior angle

Exterior angle = 180 - 168 = 12 degrees

So each exterior angle on the polygon is 12 degrees.

Now every polygon has a total of 360 degrees in exterior angles, so how many 12 degree angles fit into 360 degrees.

360/12 = 30 sides :)
