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.
