(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two forces act on an object at an angle of 50°. One force is 150 N. The resultant force is 200 N. Find the second force and the angle that it makes with the resultant, usingonlycartesian vectors.

2. Relevant equations

3. The attempt at a solution

Over here, I am very confused. We know that force one = 150 N, so therefore in two space it can be written as [150,0](horizontal on the x axis) in cartesian space. We also know that the resultant force is 200 N, and force 1, and force 2 act at an angle of 50°. I am very confused on how to find the value of force 2, and the angle that it forms with the resultant. Would we use the cosine law? Any help/suggestions to get me started would be appreciated.

Thanks!
