I can’t be sure without the diagram — “adjacent to angle D” means a side that meets at vertex D (for an acute angle it’s the non‑hypotenuse side next to D).

If this is the 5–12–13 right triangle and 13 is the hypotenuse:
- If angle D is the acute angle whose opposite side is 5, then the adjacent side is 12.
- If angle D is the acute angle whose opposite side is 12, then the adjacent side is 5.
- If angle D is the right angle, the two adjacent sides are 5 and 12.

If you upload the diagram or tell me which side is opposite D (or which side is the hypotenuse), I’ll give the single correct number.
