WebThen, this answer needs to be divided by 2 because the pictured right triangle is half of a larger isosceles triangle. 72° / 2 = 36° Marked angle is 36°. Tan (θ) = Opposite side / adjacent side. tan 36° = x / 3. 0.727 = x / 3. x = 2.181. So, side of a pentagon = 2.181. Perimeter of pentagon = 5 * side = 5 * 2.181 = 10.905
