Answer:
The magnitudes of the second force is

The magnitudes of the resultant force is

Step-by-step 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
