1. Find the height of a tree if the angle of elevation of its top changes from 20° to 40° as the observer advances 75 feet towards the base. 2. A vertical pole is 10 m from a building. When the angle of elevation of the sun is 40º, the pole cast a shadow on the building 1 m high, Find the height of the pole.
