G4a. I can solve for missing angles using inverse trigonometry 1. What is it that inverse trigonometric functions can help you find?
2. Solve for the missing angle. a) b) c)
3. Solve for the missing side of the triangle. a) b) c)
4. Solve the problem by drawing a diagram and using trigonometric ratios. a)
b)
c) Mayfield High School’s flagpole is 15 feet high. Tamara is 49.2 feet away from the flagpole. Knowing her
height is 62 inches, what is the angle of elevation from Tamara to the top of the flagpole?
d) Tamara decided to move her position. She is now looking at the flagpole at an angle of 58.4 °. How far away is she now?
***The following problems are intentionally more difficult and require more steps. They represent a move towards A-level difficulty. ***
5. Find the area of the triangle below 6. Find the area of the triangle below.
7. Find the area of the triangle below 8. Find an angle θ, where sin (θ )=cos (θ)
