"Solve problems in a variety of contexts using: ... • right triangle trigonometry."
What you'll learn
- Choose the correct trig ratio (sin, cos, or tan) based on which sides are known and unknown
- Set up and solve an equation to find a missing side using a trig ratio and a known angle
- Use inverse trig functions (sin^(-1), cos^(-1), tan^(-1)) to find a missing angle given two sides
- Solve applied right triangle problems involving angles of elevation and depression
- Interpret and solve SAT-style word problems that require trigonometric ratios
