(5) Assume that 0 is an angle in a right triangle. (a) If 0 = 30° and the side opposite 0 has length 4, how long is the side adjacent to 0? (b) If 0 = 15° and the hypotenuse has length 12, how long is the side opposite 0? (c) If 0 = 67° and the side adjacent to 0 has length 2, how long is the side opposite 0? (d) If 0 = 32.8° and the side opposite 0 has lengh 14, how long is the hypoteneuse?

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
