## Homework Statement

R is the resultant of the three forces A, B, and C, that is R = A + B + C. If

A = (A) N, 210°,

B = 200 N, Θ1,

C = 200 N, 65°,

and R = 250 N, 125°.

Use the component method to determine A and Θ1. (There may be two solutions to this one.) Check your result by adding directly using your calculator.

## The Attempt at a Solution

I don't even know. I've tried breaking this down into its components and such, but I just don't understand. Having both ungiven magnitude and direction makes this seem like the only way I can solve it is by plugging numbers. Is there something I'm missing? I'm stressing out over this one problem.
