Question

two forces act on a point at an angle of 102 degrees the first is a force of 130 pounds. if the resultant makes an angle of 38 degrees what is the magnitude of the resultant to the nearest pound

Answer 1

It seems to me like you need to know something about the second force involved, so we have something to jack around with to find out the resulting magnitude, but I'm messing around with it. I may come up with something.

Answer 2

yeah, you need something about that second force for sure, or have the magnitude of the resulting force, to find out the vectors of the second force. Either way, there are too many unkowns and not enough equivalences to figure it out. As is it breaks down to the (vector component in x of the 130lb force + an arbitrary vector component in x )+ (vector component of 130lb force in y+ an arbitrary vector component in y) = the magnitude of the resultant broken up into x and y components. By making the other force unknown in size and direction, it is impossible to figure the magnitude of the result.
