The angle of elevation to the top of a tree is 63 degrees. Given that the distance to the tree is 15 m and your height is 1.6 m, how tall is the tree?
Drawing a diagram for this would show that the height of the tree above us is given by tan(63)*15, so the total height is this added to 1.6 m. This gives a height of 31 m.
