Step-by-step explanation:
This is an equilateral triangle. That means all sides are equal and all angles are equal
An equilateral triangle has angle measurements of 60 degrees
60 =4x
Divide each side by 4
60/4 = 4x/4
15 =x
Octagon has 8 sides so the sum of the angles of the octagon is 180(8-2)=180 (6)=1080 degrees
