Sine/Cosine/Tangent practice HW

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine ratio in a right triangle?

Back

The cosine ratio is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent ratio in a right triangle?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side.

Front

How do you solve for x using the sine ratio?

Back

Use the formula: sin(θ) = opposite/hypotenuse, rearranging to find x.

Front

How do you solve for x using the cosine ratio?

Back

Use the formula: cos(θ) = adjacent/hypotenuse, rearranging to find x.

Front

How do you solve for x using the tangent ratio?

Back

Use the formula: tan(θ) = opposite/adjacent, rearranging to find x.

Front

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

Back

tan(θ) = sin(θ)/cos(θ) for any angle θ.

Front

What is the value of sin(30°)?

Back

sin(30°) = 0.5.

Front

What is the value of cos(60°)?

Back

cos(60°) = 0.5.

Front

What is the value of tan(45°)?

Back

tan(45°) = 1.
