What is the sine of angle C?

Back

The sine of angle C is the ratio of the length of the opposite side to the hypotenuse in a right triangle. For angle C, it is 24/25.

Front

What is the length of side x?

Back

The length of side x is 7.44 cm.

Front

What is the ratio for Tangent?

Back

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

Front

What is the ratio for Cosine?

Back

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

Front

What is the relationship between similar triangles?

Back

In similar triangles, the ratios of the lengths of corresponding sides are equal.

Front

Define the Pythagorean Theorem.

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

What is the formula for finding the sine of an angle?

Back

Sine(θ) = Opposite side / Hypotenuse.

Front

What is the formula for finding the cosine of an angle?

Back

Cosine(θ) = Adjacent side / Hypotenuse.

Front

What is the formula for finding the tangent of an angle?

Back

Tangent(θ) = Opposite side / Adjacent side.

Front

How do you find the length of a side in a right triangle using sine?

Back

To find the length of a side using sine, use the formula: Opposite side = Hypotenuse * Sine(θ).
