The gusset plate G of a bridge joint is subjected to the two member forces at A and B. If the force at B is horizontal and the force at A is directed at 
= 30°, determine the magnitude and direction of the resultant force.
R = 458 N, 
= 97.5° CCW
= 97.5° CCWR = 252 N, = 82.5° CCW
= 82.5° CCWR = 252 N, = 97.5° CCW
= 97.5° CCWR = 458 N, = 82.5° CCW
= 82.5° CCWDiscussion:

tan^-1(250/-33.0127).
= -82.4776 or -82.5 (since it is negative you have to subtract it from 180) 180-82.5.
= 97.5° CCW.
