Master determining the missing sides of a triangle using trig functions

The video tutorial explains how to find missing sides of right triangles using trigonometric functions. It covers the identification of triangle parts and the application of tangent, cosine, and sine functions to solve for unknown sides. The tutorial emphasizes the importance of correct labeling and calculator settings, providing step-by-step examples for each function.

What is the first step in solving for a missing side using trigonometric functions?

• Label the triangle correctly

• Use a calculator

• Identify the hypotenuse

• Calculate the angle

In a right triangle, which side is opposite the 90-degree angle?

• Base

• Opposite

• Hypotenuse

• Adjacent

Which trigonometric function is used when you have the opposite and adjacent sides?

• Sine

• Cosine

• Tangent

• Cotangent

What should you do if your calculated side length seems unreasonable?

• Ignore the result

• Check if the calculator is in degree mode

• Use a different trigonometric function

• Recalculate using radians

Which function would you use if you have the adjacent side and hypotenuse?

• Secant

• Cosine

• Tangent

• Sine

What is the result of dividing the opposite side by the hypotenuse?

• Cotangent of the angle

• Cosine of the angle

• Tangent of the angle

• Sine of the angle

If you have the opposite side and need to find the hypotenuse, which function should you use?

• Tangent

• Sine

• Cosine

• Cosecant
