  1. 13.1 Assignment C – even answers 18. sin = 4/13 34. B = 53o cos = a = 13.24 tan = b = 17.57 cot = sec = 38. A = 34o csc = 13/4 b = 10.08 c = 12.16

  2. 13.1 Quiz B Solve the right triangle using the given information. Give answers in simplest radical form if necessary.

  3. 13.2 General Angles and Radian MeasureNotes A In Lesson 13.1 you worked only with acute angles (angles measuring between 0o and 90o). In this lesson you will study angles whose measures can be any real number. An angle is formed by _____ _____ that have a common endpoint called the ___________.

  4. Initial side: Terminal side: Standard position: Measure of an angle:

  5. Example 1: Drawing Angles in Standard Position Draw an angle with the given measure in standard position and tell in which quadrant the terminal side lies. (a) 210o b) -45o c) 510o

  6. Coterminal angles: Example 2: Finding Coterminal Angles Find one positive and one negative angle that are coterminal with the given angles. a) -60o b) 495o

  8. So far, all the angles you have worked with have been measured in degrees. You can also measure angles in radians. Radian:

  9. Degrees = Radians= Example 3: Converting Between Degrees and Radians • Convert 110o b) Convert to radiansto degrees
