Trig Practice Formative

Front

What is the definition of the tangent ratio in trigonometry?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.

Front

What is the sine ratio?

Back

The sine ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

Front

What is the cosine ratio?

Back

The cosine ratio is defined as the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.

Front

How do you find the height of a building using trigonometry?

Back

You can use the tangent ratio: height = distance from the building * tan(angle of elevation).

Front

If you are 250 meters away from a building and look up at a 73 degree angle, how do you calculate the height of the building?

Back

Use the formula: height = 250 * tan(73 degrees).

Front

What is the formula to find the angle of elevation?

Back

The angle of elevation can be found using the inverse tangent function: angle = tan^(-1)(opposite/adjacent).

Front

What is the relationship between the sides of a right triangle and the angles?

Back

The sides of a right triangle are proportional to the sine, cosine, and tangent of its angles.

Front

How do you determine which trigonometric ratio to use in a problem?

Back

Identify the sides involved: use sine for opposite/hypotenuse, cosine for adjacent/hypotenuse, and tangent for opposite/adjacent.

Front

What is the value of cos(0 degrees)?

Back

The value of cos(0 degrees) is 1.

Front

What is the value of sin(90 degrees)?

Back

The value of sin(90 degrees) is 1.
