Find the missing length of a triangle using the sine function

The video tutorial explains how to solve problems using right triangle trigonometry. It covers the properties of right triangles, including the hypotenuse and legs, and introduces the concept of theta as an angle. The tutorial explains the sine, cosine, and tangent functions, and how they relate to the sides of a triangle. It demonstrates the use of these functions to solve a specific problem, showing how to calculate the length of a side using the sine function and a scientific calculator.

What is the longest side of a right triangle called?

• Theta

• Hypotenuse

• Opposite

• Adjacent

Which angle is represented by Theta in a right triangle?

• The angle adjacent to the hypotenuse

• Any angle in the triangle

• The angle opposite the hypotenuse

• The right angle

What does the mnemonic 'SOHCAHTOA' help you remember?

• The types of triangles

• The names of triangle sides

• The ratios of trigonometric functions

• The properties of angles

If you know the opposite side and hypotenuse, which trigonometric function would you use?

• Secant

• Tangent

• Sine

• Cosine

In the example problem, what is the calculated length of the opposite side?

• 11.2

• 34

• 20

• 0.56
