Finding Missing Angles in Right Triangles

The video tutorial explains how to find a missing angle in a right triangle using trigonometry. It emphasizes identifying the correct trigonometric function based on given information and solving for the angle using inverse operations. The tutorial provides step-by-step instructions on using a calculator to find the angle in degrees and encourages students to practice similar problems.

What is the main difference between the current problem and the previous one?

• We are finding a missing side length.

• We are finding a missing angle.

• We are solving for a different variable.

• We are using a different trigonometric function.

Which trigonometric function represents the ratio of the opposite side to the hypotenuse?

• Tangent

• Cotangent

• Sine

• Cosine

If the hypotenuse is not given, which trigonometric functions can we exclude?

• Tangent and Cotangent

• Sine and Cosine

• Cosine and Tangent

• Sine and Tangent

What is the trigonometric function that deals with the opposite and adjacent sides?

• Tangent

• Sine

• Secant
