Four penguins are being pulled along very slippery (frictionless) ice by a curator. The masses of the three penguins are given below and so are two of the tensions. Find the penguin mass that is not given.

12kg---Unknown--111N--15kg---20kg--222N

After drawing the free-body force diagrams, I was lost.
