Consider a frame that is made up of two thin massless rods AB and AC as shown in the figure. A vertical force $\vec{P}$ of magnitude 100 N is applied at point A of the frame.
$\begin{aligned} & {\left[\text { Given }: \sin \left(35^{\circ}\right)=0.573, \cos \left(35^{\circ}\right)=0.819\right.} \\ & \left.\sin \left(110^{\circ}\right)=0.939, \cos \left(110^{\circ}\right)=-0.342\right]\end{aligned}$
