Describe as a wordproblem a situation in which a right triangle and a trigonometric function are used to measure a height or distance that would otherwise be inconvenient or impossible to measure.

Solution

Trigonometry was first developed to measure heights and distances that were inconvenient or impossible to measure directly. In solving application problems, begin by making a sketch involving a right triangle that illustrates the problem’s conditions. Then put your knowledge of solving right triangles to work and find the required distance or height.

example: From a point on level ground 125 feet from the base of a tower, the angle of elevation is 57.2°. Approximate the height of the tower to the nearest foot?

solution: tan57.2 = a/125

a = 194
