  7. Convert 2pi/3 into degrees. 120 degrees

  8. Convert -285 degrees into radians. -19pi/12 rad.

  9. A positive angle that terminates in Quadrant III with a 80 degree reference angle. What is the rotational angle? 260 degrees

  10. A negative angle terminates in Quadrant III with a 22 degree reference angle. What is the rotational angle? -158 degrees

  11. A positive angle terminates in Quadrant II with a 15 degree reference angle. What is the rotational angle? 165 degrees

  12. A negative angle that terminates in Quadrant I with a 75 degree reference angle. What is the rotational angle? -285 degrees

  13. A positive angle that terminates in Quadrant IV with a 50 degree reference angle. What is the rotational angle? 310 degrees

  14. Rotational Angle: 2pi/3 What is the reference angle? Pi/3 or 60 degrees

  15. Rotational Angle: 11pi/2 What is the reference angle? Pi/12 or 15 degrees

  16. Rotational Angle: 5pi/6 What is the reference angle? Pi/6 or 30 degrees

  17. Rotational Angle: 17pi/12 What is the reference angle? 5pi/12 or 75 degrees

  18. Rotational Angle: 7pi/4 What is the reference angle? Pi/4 or 45 degrees

  19. Evaluate the trigonometric function for this angle: Tan(240 degrees) √(3)

  20. Evaluate the trigonometric function for this angle: Cot(150 degrees) -√(3)

  21. Evaluate the trigonometric function for this angle: Sec(315 degrees) √(2)

  22. Evaluate the trigonometric function for this angle: Csc(60 degrees) 2√(3)/3

  23. Label the quadrants where the trig ratios are positive. Quadrant I: sin, cos, tan, cot, sec, csc Quadrant II: sin, csc Quadrant III: tan, cot Quadrant IV: cos, sec

  24. What is the initial side of a circle when dealing with degrees? Initial side is the side where the rotation angle starts, located on the positive x-axis, and it is also referred to as 0.

  25. What is the difference between positive angles and negative angles? Positive angles are angles that go counter-clockwise from 0 degrees. Negative angles are angles that go clockwise from 0 degrees.

  26. Five right angles will equal to how many degrees in a circle? 450 degrees

  27. An arc of a circle is how many degrees regularly? One radian

  28. Find the sector area of the shaded part of the circle where it is covered by 240 degrees that has a radius of 8 inches? Hint: S=0.5r^2(degrees) 33pi/3 or 134.04 in^2.
