Explore the fundamentals of right triangle trigonometry in this comprehensive 43-minute lecture. Learn how to identify and calculate missing sides and angles using the basic trigonometric functions of sine (sin), cosine (cos), and tangent (tan). Begin with an introduction to working with right triangles, then progress through identifying missing sides, finding the hypotenuse, and determining angles. Apply these concepts in practical examples to solidify your understanding of right triangle trigonometry, an essential component of precalculus and trigonometry studies.
