1 - Multiple Choice 1 . What was the reference angle to 117"? [2pts each] a) 117 1. b) 2430 c) -63 d) 63 2. In which quadrant(s) in the coto > 0? 2. a) I only b) III only c) I and III d) III and IV 3. In which quadrant is coso 07 @) I b) II c) III d) IV 4. If the reference angle is 72", then the equivalent angle in 4. Quadrant III would be: a) 2520 b) 108" c) 2880 d) -72" 5. If sin (x + 20) = cos (4x - 5), which equation could be used to solve 5. for x. a) (x + 20) = (4x - 5) b) (x + 20) + (4x - 5) = 90 c) (x + 20)(4x - 5) = 0 d) (x + 20) + (4x - 5) = 180
