Answer:

  DC = 30

Step-by-step explanation:

Point D is the circumcenter of triangle ABC, so it is equidistant from A, B, and C.

We are given the measures of DE and AE, so we can figure AD using the Pythagorean theorem:

  AD² = AE² + DE² . . . . . . . . . . . . . . . E bisects AB, so AE=AB/2=18

  AD = √(18² +24²) = √900 = 30

  DC = AD

  DC = 30
