(I don't have access to a radian calculator right now), also how do they get the 19N?

Yes.So then is arctan(30/190) 9 degrees?

You don't need a radian calculator. (If ever you don't have a calculator handy, Google has one.)(I don't have access to a radian calculator right now), also how do they get the 19N?

The 19 N makes no sense. But the components are close enough, so you should be able to figure the magnitude properly from that.

So the real F is sqrt(130^2+30^2) am I correct?

Where did the 130 come from?So the real F is sqrt(130^2+30^2) am I correct?
