In order to find solution for problems involving angles of elevation & depression, it is important to
* Always use basic right triangle trigonometry
* solve equations which involve 1 fractional term is also necessary to know.
* Try to find an angle that is given a right triangle ratio of sides.
* The statement that corresponding angles formed by parallel lines have the same measure.
A distinctive problem of angles of elevation & depression involves organizing information regarding distances & angles within a right triangle. In some other cases, learner will be asked to determine the measurement of an angle; in others, the problem might be to find an unfamiliar distance.
