SOHCAHTOA Practice

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic for remembering the definitions of the sine, cosine, and tangent functions: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.

Front

What is the formula for Sine?

Back

Sine = Opposite/Hypotenuse.

Front

What is the formula for Cosine?

Back

Cosine = Adjacent/Hypotenuse.

Front

What is the formula for Tangent?

Back

Tangent = Opposite/Adjacent.

Front

If the opposite side is 8 and the hypotenuse is 10, what is sin θ?

Back

sin θ = 8/10 = 0.8.

Front

If the adjacent side is 6 and the hypotenuse is 10, what is cos θ?

Back

cos θ = 6/10 = 0.6.

Front

If the opposite side is 8 and the adjacent side is 6, what is tan θ?

Back

tan θ = 8/6 = 1.33.

Front

Find the missing angle if sin θ = 0.5.

Back

θ = 30°.

Front

Find the missing angle if cos θ = 0.6.

Back

θ = 53.13°.

Front

Find the missing angle if tan θ = 1.33.

Back

θ = 53.13°.
