Question

A right triangle has side lengths 5, 12, and 13 as shown below.

Answer 1

Answer:

sin M = $\frac{12}{13}$, tan M = $\frac{12}{5}$, cos M = $\frac{5}{13}$

Step-by-step explanation:

The sine of an angle is equal to $\frac{opposite}{hypotenuse}$.  The opposite (opposite from the angle) side is 12 and the hypotenuse is 13.

The tangent of an angle is equal to $\frac{opposite}{adjacent}$.  The opposite side is 12 and the adjacent (next to the angle) side is 5.

The cosine of an angle is equal to $\frac{adjacent}{hypotenuse}$.  The adjacent (next to the angle) side is 5 and the hypotenuse is 13.
