What is the length of each side of a regular octagon that has a total height of 85 inches.?

I'm not sure what you mean by "total height". I guess you mean the perpendicular distance between two parallel opposite sides. Draw the two diagonals to the opposite vertices from one side; they meet at the centre of the octagon, creating an isosceles triangle with the side of the octagon. The perpendicular height from the centre to the side is height/2 The angle at the centre is 360°/8 = 45° (as there are 8 such triangles). The angle at each end of the octagon side is (180° - 45°)/2 = 62.5° Drop a perpendicular from the centre of the octagon to the side of the octagon in this triangle. This forms a right angle triangle with one side height octagon/2, side octagon/2 and hypotenuse largest diagonal/2 → Tan 62.5° = (height/2) / (side/2) = height/side → side = height/tan 62.5° = 85in/tan 62.5° ≈ 44.25 in
