Answer:

sin M =
(12)/(13), tan M =
(12)/(5), cos M =
(5)/(13)

Explanation:

The sine of an angle is equal to
(opposite)/(hypotenuse). The opposite (opposite from the angle) side is 12 and the hypotenuse is 13.

The tangent of an angle is equal to
(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
(adjacent)/(hypotenuse). The adjacent (next to the angle) side is 5 and the hypotenuse is 13.
