Please solve these question in details and fully explaination. Thank you so much in advance.

1. Given that F1 = 750 N, F2 = 790 N, F3 = 605 N and or = 25, a) determine the magnitude of the resultant force in Newtons (N). b) determine the direction of the resultant force (in degrees) measured counterclockwise from the positive x-axis. If the magnitude of the resultant force acting on the bracket is to be 450 N directed along the positive u axis. Consider F2 = 200 N, F3 2 260 N and or = 30. a) determine the magnitude of F1 in Newtons (N). b) determine the direction of F1 measured counterclockwise from the positive xaxis in degrees
