The short answer

Triumph 75F is Wacoal 34DDD by the two brands' own charts.

Cups are counted along each brand's own letter order, and the band is carried across unchanged.

Every Triumph size read across to Wacoal. EU sizes on the left, US on the right.

Neither chart publishes the body each size is built for, so the rows line up the labels. Tinted rows change label or sit between two sizes. 1 sizes have no counterpart on the Wacoal chart. Read from the two charts only; no formula and no averaging.
