12. 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.
