a. The tangent function is defined as the length of the side adjacent over the length of the side opposite.

b. The sine of an angle is defined as the length of the side opposite over the length of the hypotenuse.

c.The cosine function is defined as the length of the side opposite over the length of the hypotenuse.

d.The secant of an angle is defined as the length of the side adjacent over the length of the hypotenuse.

B.) The sine of an angle is defined as the length of the side opposite over the length of the hypotenuse. (This is the correct answer).

An easy way of remembering the trigonometric ratios is by memorizing "sohcahtoa."

Sine = opposite/hypnotenuse (soh)

Cosine = adjacent/hypotenuse (cah)

Tangent = opposite/adjacent (toa)

Hope this helps! :)
