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.
