Right Triangle Trigonometry Quiz

What is the first step in solving for the length of side x in a right triangle when given an angle and one side length?

• Assume the triangle is equilateral.

• Label the sides of the triangle relative to the given angle.

• Directly use the sine ratio to find the length.

• Calculate the hypotenuse using the Pythagorean theorem.

Which trigonometric ratio is used to find the length of side x when given the opposite side and an angle?

• Sine

• Cosine

• Tangent

• Secant

After setting up the equation using the tangent ratio, what is the next step to solve for x?

• Multiply both sides by the given side length.

• Add the given side length to both sides.

• Divide both sides by the tangent of the angle.

• Subtract the angle from both sides.

In the second problem, which trigonometric ratio is used to find the length of side x?

• Cosecant

• Tangent

• Cosine

• Sine

What is the final step in calculating the length of side x using the cosine ratio?

• Subtract the cosine of the angle from the hypotenuse.

• Add the cosine of the angle to the hypotenuse.

• Multiply the hypotenuse by the cosine of the angle.

• Divide the hypotenuse by the cosine of the angle.
