CPM Homework Help : PCT Problem 1-12

For $∆ABC$ below, state each ratio in terms of the sides.

$\sin(α) = \text{ ?}$
$\cos(α) = \text{ ?}$
$\tan(α) = \text{ ?}$

Right triangle, A,B,C, short leg, A,B, labeled, small c, long leg, B,C, labeled, small a, hypotenuse, A,C, labeled small b, angle opposite long leg, labeled alpha.

Hint:

Label the sides.

Added to right triangle, side, b, labeled hypotenuse, side, a, labeled, opposite, side, c, labeled, adjacent.

Reference:

$\sin(\alpha)=\frac{\text{opposite}}{\text{hypotenuse}}$

$\cos(\alpha)=\frac{\text{adjacent}}{\text{hypotenuse}}$

$\tan(\alpha)=\frac{\text{opposite}}{\text{adjacent}}$
