In the diagram above, 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.
\(\frac{50 \sin \theta}{\sin (\theta + 45)°}\)
