Tangent = Opposite / Adjacent we want to find the opposite so we call it x, and we have the adjacent side to 67 which is 137 feet so.... tan(67) = x/ 137 multiply both sides by 137 to leave x alone (or cross multiply) then you'll get..... x = 137 * tan(67) x = 322.75 feet The pole's height = 322.75 feet :) hope it helps:)
