2. Section 4.2 Mrs. Ramsey

6. Right Triangle Trig: Find all 6 trig functions for angle B: Find all 6 trig functions for angle B: Let c = 33 and b = 18 Let c = 33 and b = 18

7. Right Triangle Trig: Find all 6 trig functions for angle C: Find all 6 trig functions for angle C: Let a = 1 and c = 2 Let a = 1 and c = 2

8. Solving Triangles Solve the triangle if c=8 and A = 37º Solve the triangle if c=8 and A = 37º A =a = B =b = C =c =

9. Elevation and Depression:

10. Another example… From a point 340 ft away, the angle of elevation to the top of a building is 65º. Find the height of the building. From a point 340 ft away, the angle of elevation to the top of a building is 65º. Find the height of the building.

11. Just to add…FYI - cot.89 = cot.89 = Inverse on calc: Inverse on calc: Sin Ө = 1/2 Sin Ө = 1/2
