How to apply sine to find the missing side of a triangle

The video tutorial explains how to solve a trigonometry problem involving a right triangle. The teacher guides students through identifying the hypotenuse, adjacent, and opposite sides of the triangle. The focus is on using the sine function to find the length of the opposite side when given an angle and the hypotenuse. The teacher also briefly discusses the roles of cosine and tangent in trigonometry.

What is the relationship between the adjacent side and the right angle in a triangle?

How do you determine which side is the opposite side in relation to a given angle?

What is the sine of an angle defined as in terms of opposite and hypotenuse?

How do you solve for X when given the sine of an angle and the hypotenuse?

Why can you only use the sine function to find X in this problem?
