## Trigonometry (10th Edition)

1. 90-180 degrees in the second quadrant. Therefore 90$^{\circ}$$\leq174^{\circ}$$\leq$180$^{\circ}$ its in the second quadrant 2. Coterminal angles always in the same quadrant with original angle, because of full resolutions (2$\pi$) 174° + 360° = 534° 174° - 360° = -186°
