  1. Chapter 9

  2. COMPLETE THE RATIO: 10 Tan x = _____ 6 x 8

  3. 6 __ Tan x = 8

  4. COMPLETE THE RATIO: 10 Sin x = _____ 6 x 8

  5. 6 ___ Sin x = 10

  6. COMPLETE THE RATIO: 10 Cos x = _____ 6 x 8

  7. 8 ___ Cos x = 10

  8. What does“SOH CAH TOA”stand for?

  9. Opposite Leg _____________ Sin =Cos =Tan = Hypotenuse Adjacent Leg _____________ Hypotenuse Opposite Leg ____________ Adjacent Leg

  10. A surveyor stands 200 feet from a building to measure its height with a 5 foot tall theodolite. The angle of elevation to the top of the building is 35 degrees. How tall is the building?

  11. Tan 35 = x/200 x = 140 x 145 ft 350 200 5

  12. An airplane flying 3500 feet above ground begins a 2 degree descent to land at an airport. How many miles from the airport is the airplane when it starts its descent?

  13. Sin 20 = 3500/x x = 100,288 ft or 19 miles 20 3500 x

  14. COMPLETE THE RATIO: Cot x = _____ 10 6 x 8

  15. Cot x = 8/6 10 6 x 8

  16. COMPLETE THE RATIO: Csc x = _____ 10 6 x 8

  17. Csc x = 10/6 10 6 x 8

  18. COMPLETE THE RATIO: Sec x = _____ 10 6 x 8

  19. Sec x = 10/8 10 6 x 8

  20. COMPLETE: 1) sin2 + cos2 = _____ 2) sin/cos = _____ 3) (sin)(_____) = 1

  21. 1) sin2 + cos2 = 1 • 2) sin/cos = tan • 3) (sin)( csc ) = 1

  22. REVIEWFactor: 2x2 + 3x - 5

  23. 2x2 + 3x - 5 = (2x + 5)(x - 1)
