Answer:
The magnitudes of the second force is 
The magnitudes of the resultant force is 
Explanation:
From the question we are told that
The force is 
The angle made with second force 
The angle between the resultant force and the first force 
For us to solve problem we are going to assume that
The magnitude of the second force is Z N
The magnitude of the resultant force is R N
According to Sine rule

Substituting values

According to cosine rule

Substituting values
