A)45 = (45/180)π = (1/4)π = π/4
B)135 = 180 -45= π -π/4 = 4•π-π/4= 3π/4
C) 210=180+30= π +π/4 =4•π+π/4=5π/4
D)300=360-60= 2π -π/3=2π•3-π/3=5π/3
E)330=360-30=2π -π/6=2π•6-π/6=11π/6
B)135 = 180 -45= π -π/4 = 4•π-π/4= 3π/4
C) 210=180+30= π +π/4 =4•π+π/4=5π/4
D)300=360-60= 2π -π/3=2π•3-π/3=5π/3
E)330=360-30=2π -π/6=2π•6-π/6=11π/6
