Resolution of Forces

Q. Two forces are acting on a point at an angle of $\alpha$ and $\beta$ as shown in figure. If the sum of these forces is 700 N directed vertically, What are the angles $\alpha$ and $\beta$?

1. $\alpha ={55.95}^{\circ },\beta ={45.58}^{\circ }$
2. $\alpha ={45.58}^{\circ },\beta ={55.95}^{\circ }$
3. $\alpha ={90}^{\circ },\beta ={30}^{\circ }$
4. $\alpha ={40.166}^{\circ },\beta ={53.73}^{\circ }$
