i fully understand how to find the resultant when given the forces but do not know how to find the forces when given the resultant.

my question is...what are the forces and how do i find them.

F₁ and F₂ are the forces and R is the resultant.

The easiest thing to do is to put $\Sigma F_x =R_x \ and \ \Sigma F_y = R_y$
