Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of $97\mathrm{.}7N,$ Jill pulls with $98\mathrm{.}1N$ in a direction $45$ to the left, and Jane pulls in a direction $45$ to the right with $155N.($Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?$)$

Determine the magnitude $F$ of the net force the people exert on the donkey.

$F=$

What is the direction $$ of the net force? Let $0$ define straight ahead, with positive angles to the left and negative angles to the right. Express $$ as an angle with a magnitude between $0$

$=$

and $90.$
