Answer 1

Answer:

Quadrant determined

Step-by-step explanation:

if 360° is added or subtracted from any angle the Quadrant does not get Change

0-90 1st Quadrant

90-180 - 2nd Quadrant

180-270 3rd Quadrant

270-360 4th Quadrant

iii)  420° = 360° + 60°    60° lies in 1st Quadrant

iv) 750°  = 2 * 360° + 30°    30° lies in 1st Quadrant

v) 945º  = 2 * 360° + 225°    225° lies in 3rd Quadrant

vi) 1120° = 3 * 360° + 40°    40° lies in 1st Quadrant

vii) -80° = -360° + 280°     280° lies in 4th Quadrant

viii) -330° = -360° + 30°     30° lies in 1st Quadrant

ix) -500°   =  -2 * 360° + 220°     220° lies in 3rd Quadrant

x) -820°​   = - 3 * 360° + 260°     260° lies in 3rd Quadrant
