PRE CALC HELP - **PIC INCLUDED** Juana and Diego Gonzales, ages six and four respectively, own a strong and stubborn puppy named Corporal. It is so hard to take Corporal for a walk that they devise a scheme to use two leashes. If Juana and Diego pull with forces of 23 lb and 27 lb at the angles shown in the figure, how hard is Corporal pulling if the puppy holds the children at a standstill?

\[\sqrt{27^2+23^2-2*27*23*\cos(147)}=47.36lb\]
