Noah wants to find the height of an oak tree in his garden. He decides he needs to make a clinometer in order to measure the angle of elevation. He uses a straw, a protractor, some string, and a bit of Blu-Tack as a weight. Noah stands at a perpendicular distance of 85 ft from the base of the tree and measures the angle on his clinometer to be as seen in the diagram. Given that Noahâ€™s eyeline is 6 ft from the ground, work out the height of the tree to the nearest foot.
