Question

Polygon ABCDEFGHIJKL is a regular dodecagon (12-sided polygon). Sides EF and GH are extended so that they meet at point O in the exterior of the polygon. How do you find m 13 years ago

Answer 1

First, notice that the triangle formed is an isoceles triangle with exterior angles for base angles

Answer 2

The exterior angle is 360/12=30 degrees

Answer 3

So because the angles of a triangle add up to 180, 30+30+x=180

Answer 4

So the angle FOG is 120 degrees

Answer 5
