Chapter 64, Problem 25A

The sides of each of the following right triangles are labeled with different letters. State the ratio of each of the six functions in relation to $\angle 1$for each of the triangles. For example, for the triangle in Exercise 23, $\sin \angle 1\frac{y}{r},\cos \angle 1\frac{x}{r},\tan \angle 1\frac{y}{x},\cot \angle 1\frac{x}{y},\sec \angle 1\frac{r}{x},$and $\csc \angle 1\frac{r}{y}.$
