Answer

$ 60^{\circ}$

Work Step by Step

Given angle = $ -300^{\circ}$ In figure 24, we can see that terminal position corresponding to $ -300^{\circ}$ from positive side is $ 60^{\circ}$ Therefore angle coterminal with $ -300^{\circ}$ between $0^{\circ}$ and $360^{\circ}$ = $ 60^{\circ}$ Cross checking- Angle coterminal with $ -300^{\circ}$ between $0^{\circ}$ and $360^{\circ}$ = $ -300^{\circ} + 360$ = $ 60^{\circ}$
