SOH CAH TOA

Front

What does SOH CAH TOA stand for?

Back

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

Front

What type of triangle is used with trigonometric ratios?

Back

Right triangle

Front

How do you find the cosine of an angle in a right triangle?

Back

Cosine of an angle = Length of the adjacent side / Length of the hypotenuse.

Front

If cos(47) = 28/x, what is the relationship between x and the sides of the triangle?

Back

x = 28 / cos(47) (where x is the length of the hypotenuse).

Front

What is the formula for finding the sine of an angle in a right triangle?

Back

Sine of an angle = Length of the opposite side / Length of the hypotenuse.

Front

If tan(X) = Opposite / Adjacent, what is tan(47) if the opposite side is 32 and the adjacent side is 24?

Back

tan(47) = 32 / 24.

Front

What is the value of sinA if the opposite side is 32 and the hypotenuse is 40?

Back

sinA = 32 / 40.

Front

What is the value of cosA if the adjacent side is 30 and the hypotenuse is 34?

Back

cosA = 30 / 34.

Front

What is the relationship between sine, cosine, and tangent?

Back

Tangent can be expressed as the ratio of sine to cosine: tan(θ) = sin(θ) / cos(θ).

Front

How can you find the length of a side in a right triangle using trigonometric ratios?

Back

Use the appropriate trigonometric function (sine, cosine, or tangent) based on the known sides and the angle.
