Construction of Angle Bisector

Q. An angle of measure ${75}^{\circ }$ can be drawn by drawing:

1. ${90}^{\circ }$ and ${60}^{\circ }$ and bisecting the angle between them.
2. ${180}^{\circ }$ and ${60}^{\circ }$ and bisecting the angle between them.
3. ${270}^{\circ }$ and ${60}^{\circ }$ and bisecting the angle between them.
4. ${90}^{\circ }$ and ${30}^{\circ }$ and bisecting the angle between them.
