Front

What is the purpose of inverse trigonometric functions?

Back

Inverse trigonometric functions are used to find the angle measures when the lengths of the sides of a right triangle are known.

Front

How do you calculate the sine of an angle in a right triangle?

Back

Sine of an angle is calculated as the length of the opposite side divided by the length of the hypotenuse.

Front

How do you calculate the cosine of an angle in a right triangle?

Back

Cosine of an angle is calculated as the length of the adjacent side divided by the length of the hypotenuse.

Front

How do you calculate the tangent of an angle in a right triangle?

Back

Tangent of an angle is calculated as the length of the opposite side divided by the length of the adjacent side.

Front

What is the longest side of a right triangle called?

Back

The longest side of a right triangle is called the hypotenuse.

Front

If the cosine of an angle is 9/20, how can you find the angle?

Back

You can find the angle by using the inverse cosine function: θ = cos^-1(9/20).
