Miss Weiss teaches how to use trigonometry to find missing angles in right triangles. The lesson covers labeling triangles, using SOHCAHTOA to write trig ratios, and solving real-world problems. The process involves drawing diagrams, choosing appropriate trig functions, and using inverse functions to find angles. Examples include solving for angles in triangles QRS and IJK, and a real-world ladder problem.

What is the primary focus of today's lesson?

• Graphing linear functions

• Finding missing angles of right triangles

• Solving quadratic equations

• Finding missing sides of right triangles
