"distance between foci 4/3squareroot of 33"----
That means the foci are (-(2/3)sqrt(33),0) and ((2/3)sqrt(33),0). Use the distance formula to make the expression for the sum of the distances (-(2/3)sqrt(33),0) to (2,1) and ((2/3)sqrt(33),0) to (2,1). That sum will be equal to 2*a, so you will be able to get a value for a.

Next, you find b.
Use the triangle relationship, . You already know the value for c,
, and you already just found a.
