any help would be fantastic:) im so confused with this problem
Let x= magnitude x= root(150^2+75^2-2(150)(75)cos(60)) x= 75(root3) ^this is what i have so far... i dont think its even remotely right
just analyze them into x component and y component and add them with respecting to signs and the direction is simply the angle.
can you explain how to do that? i have no clue what im doing :P
