Review Tangent Sine Cosine Part 1

Front

What is the tangent ratio in a right triangle?

Back

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

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is 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 the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

How do you find the value of tan A if you know the lengths of the opposite and adjacent sides?

Back

Use the formula tan A = opposite/adjacent.

Front

If sin C = 3/5, what is the length of the opposite side if the hypotenuse is 10?

Back

The length of the opposite side is 6 (since 3/5 = x/10, x = 6).

Front

If cos z = 4/5, what is the length of the adjacent side if the hypotenuse is 15?

Back

The length of the adjacent side is 12 (since 4/5 = x/15, x = 12).

Front

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

Back

tan A = sin A / cos A.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

If the opposite side is 21 and the adjacent side is 20, what is tan A?

Back

tan A = 21/20.

Front

What is the value of sin 30°?

Back

sin 30° = 1/2.
