5. Trigonometric Functions

Given the right triangle below, evaluate $\cos \theta$.

Given the right triangle below, evaluate $\tan \theta$.

If $\tan \theta =\frac{12}{5}$, find the values of the five other trigonometric functions. Rationalize the denominators if necessary.

If $\sin \theta =\frac{\sqrt{17}}{17}$, find the values of the five other trigonometric functions. Rationalize the denominators if necessary.
