In the diagram below, forces P, Q and 50N are acting on a body at M. If the system is in equilibrium, calculate, in terms of \(\theta\), the magnitude of P.
- A. \(\frac{50 \cos \theta}{\sin (\theta + 45)°}\)
- B. \(\frac{50 \cos \theta}{\cos (\theta + 45)°}\)
- C. \(\frac{50 \sin \theta}{\cos (\theta + 45)°}\)
- D. \(\frac{50 \sin \theta}{\sin (\theta + 45)°}\)
Correct Answer: D. \(\frac{50 \sin \theta}{\sin (\theta + 45)°}\)
