Chapter 6 - 6.1 - Angles and Their Measure - 6.1 Exercises - Page 430: 15

Part A: Quadrant II Part B: Quadrant IV

Quadrant I has angles $0^{o}$ through $90^{o}$ Quadrant II has angles $90^{o}$ through $180^{o}$ Quadrant III has angles $180^{o}$ through $270^{o}$ Quadrant IV has angles $270^{o}$ through $360^{o}$ Part A: Quadrant II because $90^{o} \leq 130^{o} \leq 180^{o}$ Part B: Quadrant IV because $270^{o} \leq 285^{o} \leq 360^{o}$
