In this video, Stefan, a math professional, explains how to find the lengths of the sides of a right triangle using its interior angles. Given a right triangle with a hypotenuse of 10 and an angle of 37 degrees, he demonstrates how to calculate the adjacent side using the cosine function and the opposite side using the sine function. The video concludes with a summary of the calculated side lengths.
