Sine, Cosine, and Tangent Ratio

• sin Z

• cos Z

• tan Z

Match the following

• 6/8

• Sin(37^o)

• 8/10

• Cos(37^o)

• 6/10

• Tan(37^o)

What does SOH stand for

• sine is the hypotenuse over opposite

• sine is the opposite over adjacent

• sine is the opposite over hypotenuse

If you are given the opposite side and hypotenuse, which trig function should you use?

• sine

• cosine

• tangent

• cotangent

Which trigonometric ratio is correct?

• sin A = opposite / adjacent

• cos A = opposite / hypotenuse

• tan A = opposite / adjacent

• sin A = adjacent / opposite

From ∠C, what side is AB?

• Adjacent

• Hypotenuse

• Opposite

cos X = ?

• ¹⁵/₁₇

• ⁸/₁₇

• ¹⁷/₈

• ¹⁵/₈

Which ratio is correct?

• sin Z = 5 / 13

• tan Z = 12 / 5

• cos X = 13 / 12

• sin X = 5 / 13

Choose the correct equation that would solve for x.

• sin (37) = x / 14

• cos (37) = x / 14

• tan (37) = x / 14

• sin (37) = 14 / x
