Trigonometric Functions and Applications

This video tutorial covers right triangle trigonometry, starting with an introduction to the Pythagorean theorem. It provides examples of finding trigonometric functions for a given angle in a right triangle and solving right triangles by determining missing sides and angles. The tutorial includes step-by-step examples and concludes with a final example to reinforce the concepts.

What is the sum of all angles in a triangle?

• 360 degrees

• 90 degrees

• 180 degrees

• 270 degrees

In a right triangle, if one angle is 90 degrees, what must the sum of the other two angles be?

• 90 degrees

• 120 degrees

• 45 degrees

• 60 degrees

What is the Pythagorean theorem formula?

• a^2 + b^2 = c^2
