Answer:
f = 45°
Explanation:
- A regular octagon has an angle represented by 3f. Determine the value of f.
A regular octagon shape has eight equal sides and eight equal angles. All the sides are of equal length, and all the angles are of equal measure. The sum of the interior angles is 1080°, and the sum of the exterior angles is 360°. In a regular octagon, the interior angle at each vertex is 135°.
so
3f = 135
f = 135 : 3
f = 45°
