sin cos tan

Front

What does the sine ratio represent in a right triangle?

Back

The sine ratio represents the ratio of the length of the opposite leg to the length of the hypotenuse.

Front

How do you find the measure of a missing angle in a right triangle using sine?

Back

You can use the inverse sine function (sin⁻¹) on the ratio of the opposite leg to the hypotenuse.

Front

What is the sine ratio formula?

Back

Sine ratio = opposite leg / hypotenuse.

Front

What is the cosine ratio in a right triangle?

Back

The cosine ratio represents the ratio of the length of the adjacent leg to the length of the hypotenuse.

Front

What is the tangent ratio in a right triangle?

Back

The tangent ratio represents the ratio of the length of the opposite leg to the length of the adjacent leg.

Front

How do you calculate the angle using the tangent ratio?

Back

You can use the inverse tangent function (tan⁻¹) on the ratio of the opposite leg to the adjacent leg.

Front

What is the relationship between sine, cosine, and tangent in a right triangle?

Back

Tangent = Sine / Cosine.

Front

If the opposite leg is 40 and the hypotenuse is 41, what is the sine ratio?

Back

The sine ratio is 40/41.

Front

How do you round an angle to the nearest tenth?

Back

Look at the hundredths place; if it's 5 or more, round up.

Front

What is the value of sin(49°)?

Back

Approximately 0.7547.
