I think I got the right answer. Thanks everyone.

I did not know that thanks! I am just starting with math and science, not even in college yet. Should I use arccosine instead?

tan θ = 74.98/-15 right? then to find θ , arctan(74.98/-15)=θ, the angle is somehow negative and does not match my prediction that the wreckage will be heading to the 2nd quadrant.

Xcomp: [-(1500kg)(100km/h)(sin(30))+(3500kg)(70km/h)(cos(90))]/5000kg = -15km/h ycomp: [(1500kg)(100km/h)(cos(30))+(350(70km/h)(sin(90))]/5000kg = 74.98km/h
