Part A: Quadrant I Part B: Quadrant III

Work Step by Step

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 I because $0^{o} \leq 8.3^{o} \leq 90^{o}$ Part B: Quadrant III because $180^{o} \leq 257^{o}30' \leq 270^{o}$
