In this problem, we are asked to prove that OCl2 is polar. The VSEPR model of OCl2 is bent. Cl has an electornegativity of 3.16 while O has an electronegativity of 3.44. In this case, we add the two individual dipole moments because they are vectors. Since the sum is equal to greater than 0.5, the molecule should have to be polar.
