Since triangle ABC is equilateral, all sides are the same length. Therefore each side, including, of course, side BC, is 72/3 = 24. Side AB is also 24.

Side BC forms the base of isoceles triangle DBC, which has a perimeter of 50. Since we know that side BC is 24, then the sum of sides BD and CD is 50 - 24 = 26. And since DBC is isoceles, then BD = CD = 26/2 = 13

AB + BD = 24 + 13 = 37

Yes, I am smart enough to figure this out as long as it's not a trick question. AB+BD is 37. Then again I might be wrong because this question is not phrased very well.
