• tangent

From ∠C, what side is AB?

• Adjacent

• Hypotenuse

• Opposite

If you are given the two sides that are NOT the hypotenuse, which trig function should you use?

• sine

• cosine

• tangent

• cotangent

If you are given the length of a hypotenuse and the length of an adjacent side, what trigonometry ratio could you use .

• sine

• cosine

• tangent

• trigonometry

The ratio of the length of the side opposite of the angle to the length of the hypotenuse is the _____________

• Sine

• Cosine

• Tangent

What is the correct ratio set up for finding the tangent of Angle A? Remember: Tangent = opposite/adjacent

• 20/12

• 12/20

• 12/16

• 16/12

The ratio in a right triangle of adjacent to hypotenuse is _____

• sine

• cosine

• tangent

• inverse cosine

What is the correct set up for the problem to solve for side w?

• sin 40 = w/28

• cos 40 = w/28

• tan 40 = w/28

• sin 40 = 28/w

Choose the correct set up to find the length of the side x.
