Front

If the opposite side is 3 and the hypotenuse is 5, what is the sine of the angle?

Back

Sine = 3/5 = 0.6.

Front

If the adjacent side is 4 and the hypotenuse is 5, what is the cosine of the angle?

Back

Cosine = 4/5 = 0.8.

Front

If the opposite side is 3 and the adjacent side is 4, what is the tangent of the angle?

Back

Tangent = 3/4 = 0.75.
