Using trig functions to find the values of a triangle

The video tutorial covers solving a triangle problem by finding missing angles and sides using geometry and trigonometry. It explains the sum of angles in a triangle, the use of tangent, sine, and cosine functions, and different methods to calculate the hypotenuse, including the Pythagorean theorem. The tutorial emphasizes that multiple approaches can yield the same result.

Explain how to calculate the length of side A using the tangent of angle A.

What is the Pythagorean theorem and how can it be applied to find the hypotenuse of a triangle?

Describe the relationship between sine, cosine, and the sides of a triangle.
