Answer:
1. 135 degrees
2. 67.5 degrees
3. 6
Step-by-step explanation:
This is an 8 sided figure. Therefore the triangle is 1/8 of the octagon. A regular octagon 1080 degrees. So angle FHE is 1/8 of this or 135 degrees.
Line HG is a perpendicular bisector that divide both the angle FHE and the line FE into two equal segments. This means angle FHG is half of 135 which is 67.5 degrees.
Line FE is 12 so half will be 6.
