Front

What does SohCahToa represent in trigonometry?

Back

SohCahToa is a mnemonic for remembering the definitions of sine, cosine, and tangent in a right triangle: - SOH: Sine = Opposite/Hypotenuse - CAH: Cosine = Adjacent/Hypotenuse - TOA: Tangent = Opposite/Adjacent

Front

Find cosC if the adjacent side is 16 and the hypotenuse is 34.

Back

cosC = Adjacent/Hypotenuse = 16/34

Front

Find sinC if the opposite side is 28 and the hypotenuse is 35.

Back

sinC = Opposite/Hypotenuse = 28/35

Front

Find sinA if the opposite side is 32 and the hypotenuse is 40.

Back

sinA = Opposite/Hypotenuse = 32/40

Front

Find tanZ if the opposite side is 21 and the adjacent side is 28.

Back

tanZ = Opposite/Adjacent = 21/28

Front

What is the formula for sine in a right triangle?

Back

Sine = Opposite/Hypotenuse

Front

What is the formula for cosine in a right triangle?

Back

Cosine = Adjacent/Hypotenuse

Front

What is the formula for tangent in a right triangle?

Back

Tangent = Opposite/Adjacent

Front

If the hypotenuse is 50 and the opposite side is 30, find sinB.

Back

sinB = Opposite/Hypotenuse = 30/50

Front

If the adjacent side is 40 and the hypotenuse is 50, find cosB.

Back

cosB = Adjacent/Hypotenuse = 40/50
