pls solve this question correctly in 10 min i will give u thumsup definitely

Determine the magnitude F and direction @ (measured clockwise from the positive y-axis which is downward in this case) that will cause the resultant R of the four applied forces to be directed to the right with a magnitude of 12.4 kN. 11.1 KN 16.6 KN "1 KN Superscript 36 The asymmetric simple truss is loaded as shown. Determine the reactions at A and D. Neglect the weight of the structure compared with the applied loads. Is the knowledge of the size of the structure necessary? -X C 2L 1L 60 60 609 30
