CRM (S25): Trig & Pyth Thm Test

Front

What is the cosine of angle A if Cos(A) = 0.4706?

Back

Cos(A) = 0.4706 is the ratio of the adjacent side to the hypotenuse in a right triangle.

Front

Which trigonometric function is used when given the opposite side and the hypotenuse?

Back

The sine function (sin) is used when given the opposite side and the hypotenuse.

Front

How do you find the missing side in a right triangle?

Back

Use the Pythagorean theorem: a² + b² = c², where c is the hypotenuse.

Front

Which trigonometric function is used when given the two sides that are not the hypotenuse?

Back

The tangent function (tan) is used when given the two sides that are not the hypotenuse.

Front

What is the sine ratio for angle 33 degrees in relation to side x and hypotenuse 14?

Back

sin(33) = x/14, where x is the length of the opposite side.

Front

Define the sine function in terms of a right triangle.

Back

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

Front

Define the cosine function in terms of a right triangle.

Back

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

Front

Define the tangent function in terms of a right triangle.

Back

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

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, a² + b² = c², where c is the hypotenuse.

Front

If the opposite side is 5 and the hypotenuse is 13, what is sin(A)?

Back

sin(A) = opposite/hypotenuse = 5/13.
