balandron [24]

Answer:

330.4 N and  95.2^{\circ}counterclocwise to the x direction

Explanation:

Sum of forces in vertical are equal, let movement to right and upwards be positive while left and downwards be negative

Net force in horizontal direction is 85-115=-30 N

Net force in vertical direction is 565-236=329 N

Resultant force=\sqrt {(-30)^{2}+329^{2}}=330.3649497 N\approx 330.4 N

Direction=tan^{-1}\frac {329}{-30}=-84.78986932\approx -84.8^{\circ}

180-84.8=95.2

Therefore, direction is 95.2^{\circ}counterclocwise to the x direction
