John and Danny, own a strong and stubborn puppy named Dexter. It is so hard to take Dexter for a walk that they devise a scheme to use 2 leashes. If John and Danny pull with forces of 23 lbs and 27 lbs at the angles shown, how hard is Dexter pulling if the puppy holds the children at a standstill?

Hint: see notes pg 69 ex 5

• 50 lbs

• 47.954 lbs

• 48.073 lbs

• 48.461 lbs
