TODAY IN GEOMETRY…  Review: Methods solving for missing sides of a right triangle  Learning Target: 7.6 Finding an angle using inverse Trigonometry  Independent Practice

Basic Trig Problems in 3 categories: Pythagorean Theorem Special Right Triangles: 30-60-90 45-45-90 Trig Ratios: Sin, Cos, Tan

PRACTICE: Identify what category this problem lies in (Pythagorean, Special Right Triangles, or Trig Ratios). Solve for the missing variables.

PRACTICE: Identify what category this problem lies in (Pythagorean, Special Right Triangles, or Trig Ratios). Solve for the missing variable. Given two sides: Pythagorean Theorem

PRACTICE: Identify what category this problem lies in (Pythagorean, Special Right Triangles, or Trig Ratios). Solve for the missing variable. Given one side and an angle: Trig Ratios

Which method would you use to find the missing sides of the right triangle (Pythagorean Theorem, Special Right Triangles, or Trig)?

Find Trigonometric angles using inverse

TRIGONOMETRIC RATIOS:

METHOD TO FIND TRIG ANGLES: 1. Find the opposite, adjacent and hypotenuse of your right triangle. 2. Use the trig function that contains the sides of your triangle. 3. Use the inverse trig function to calculate the angle.

PRACTICE: Find angle x using inverse trigonometric functions. Round your answer to the nearest hundredth.

There are multiple ways to solve this problem, you may choose any trig function because all sides are given!
