Right Triangle Solving Quiz

What is the primary goal when solving right triangles in trigonometry?

• To find the area of the triangle

• To determine the missing angles and sides

• To calculate the perimeter of the triangle

• To identify the type of triangle

Which trigonometric ratio is used when you have the adjacent side and hypotenuse?

• Secant

• Tangent

• Sine

• Cosine

What is the first step in using a calculator to find an angle with the cosine ratio?

• Press the tangent button

• Press the sine button

• Press the equal sign

• Press the shift and then cosine button

What is the angle measurement if the cosine of the angle is 12/13?

• 60 degrees

• 22 degrees 37 minutes

• 30 degrees

• 45 degrees

When using the tangent ratio, which sides of the triangle are involved?

• Opposite and adjacent

• All three sides

• Adjacent and hypotenuse

• Opposite and hypotenuse

If the tangent of an angle is 11.9/10, what is the angle measurement?

• 60 degrees

• 49 degrees 57 minutes

• 45 degrees

• 30 degrees

How do you isolate the variable when solving for a side using the tangent ratio?

• Subtract the adjacent side

• Add the sides together

• Multiply both sides by the hypotenuse

• Cross multiply and divide

Which trigonometric function is used when you have the hypotenuse and need to find the adjacent side?

• Cosine

• Tangent

• Cosecant

• Sine

What is the result of dividing the adjacent side by the hypotenuse in a right triangle?

• Tangent of the angle

• Cosine of the angle

• Sine of the angle

• Cotangent of the angle
