Answer:
30°
Step-by-step explanation:
4560° ÷360°= 12.667 (5 s.f.)
This means that the angle 4560° goes around from quadrant I to quadrant IV 12 times, before coming back to quadrant I. The 13th round does not reach quadrant IV.
So, let's find the angle covered after the 12 full rounds.
12 ×360°= 4320°
remaining angle left
= 4560° -4320°
= 240°
See the attached picture to see where 240° will lie in the quadrants. It lies in quadrant III and its reference angle is the red coloured angle in the picture.
Reference angle
= 270° -240°
= 30°
