How to solve the missing length of a triangle using tangent

The teacher reviews the plan for the next class, focusing on trigonometric functions related to triangles. The lesson covers angles, hypotenuse, adjacent, and opposite sides, and explains the sine, cosine, and tangent ratios. The teacher demonstrates solving for X using the tangent of 60 degrees, emphasizing the importance of using a calculator in degree mode. The final answer is calculated, concluding the lesson.

What topic was supposed to be covered in the last class according to the teacher?

• Trigonometric functions based on triangles

• Calculus derivatives

• Algebraic equations

• Unit circle

In a right triangle, what is the side opposite the right angle called?

• Opposite side

• Hypotenuse

• Base

• Adjacent side

Which trigonometric function is defined as the ratio of the opposite side to the hypotenuse?

• Tangent

• Sine

• Secant

• Cosine

What is the equation set up to solve for X using the tangent function in the example?

• tan(60) = 32 / X

• tan(60) = X / 32

• tan(60) = X * 32

• tan(60) = 32 + X

Before using a calculator to find the value of X, what mode should it be set to?

• Radians

• Gradians

• Degrees

• Scientific
