She is standing on the ground at some distance from the tree and measures an angle of 63 degrees to the top of the tree. She walks 20 feet further away from the tree and measures an angle of 50 degrees to the top of the tree (this is her second measurement). A year later she comes back to check on the tree and it has grown. She measures the angle from the same location as the second measurement from the year before and now gets an angle of 52 degrees. How much taller is the tree: a weight is attached to a spring suspended from the ceiling. The height h(t) of the weight is a sinusoidal function of time t. at time t = 5 seconds, the weight is at its lowest height of 15 cm.
