Find the length of AB, given that DB is a median of the triangle and AC=52

The length of segment AB=64 and so does segment DB. The triangle has to equal up to 180 no matter if its lines or angles. If you take 52 and subtract it from 180, then you get 128. Once you have 128 you divide it by two, that would equal half of it. So it would be 64 for the sides that aren't numbered, which is AB and DB
