Determine the reading of F on the spring balance by using a scale diagram

2. Relevant equations

None

3. The attempt at a solution

Am I doing it correctly?
It doesn’t really make sense to me. I can’t determine the force F. I only have 30degree angle and the weight.
I don’t know how to draw the length of Force F. What is it should I be looking for?

Thank you!
