Cathy stands at point Cand uses a survey instrument to measure the angle of elevation to the top of the flagpole, and determines it to be 34.9º. She walks a few meters closer to point B, and
determines the new measure of the angle of elevation to be 52.8°. The height of the flagpole is
13.6m. Determine and state, to the nearest tenth of a meter, the distance between Cathy's two
angle measurements (BC).
