The Problem
Stellar Steve is an MMA fighter who wants to build his octagon shaped ring to practise in. He has 8 sides of the ring and needs to get the right angle for where each side joins. He has searched up that the angle of each join is 140 degrees. However when he builds his ring, all the sides don't fit together. Show, with working, what the correct angle should be.
Hint: Steve doesn't have a growth mindset for math so you may want to show him the pattern of interior angles for triangles, squares, pentagons etc.
