use the component method to determine A and Theta(there may be 2 solutions)
So
Ax= A cos 30
Ay= A sin 30
Bx=200 cos Theta(possibly could be switched)
By=200 sin Theta
Cx=200 cos 65 = 84.5
Cy=200 sin 65 = 181
Rx=250 sin 35 = 114.7
Ry=250 cos 35 = 204.7
A cos 30 + 200 cos Theta = 30.2
is this the correct way to do this problem? Where would I go from here since I have 2 variables? any help to give me a shove would be appreciated.
