Right triangle trigonometry

This study guide covers right triangle trigonometry for the AP SAT (Digital), including SOH-CAH-TOA, reciprocal functions (cosecant, secant, cotangent), the Pythagorean theorem, and angle relationships. It explains how to solve for missing side lengths and angles using trigonometric ratios and inverse functions, and also covers angles of elevation and depression. Finally, it reviews special right triangles (30-60-90 and 45-45-90) and their properties for efficient problem-solving.
