2. Trigonometric Functions on Right Triangles

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.

Given the right triangle below, use the sine function to write a trigonometric expression for the missing angle $\theta$.

Given the right triangle below, use the cosine function to write a trigonometric expression for the missing angle $\phi$.
