I’m missing the triangle type or angle — can you confirm whether this is a right triangle and which side (if any) is the hypotenuse?

Possible interpretations:

- If 13 and 9 are the two legs of a right triangle, the hypotenuse = sqrt(13^2 + 9^2) = sqrt(250) = 5√10 ≈ 15.8.
- If 13 is the hypotenuse and 9 is one leg of a right triangle, the other leg = sqrt(13^2 − 9^2) = sqrt(88) ≈ 9.4.
- If you only know two side lengths (13 and 9) with no angle, the third side x can be any number satisfying the triangle inequality: |13 − 9| < x < 13 + 9, i.e. 4 < x < 22.

Tell me which case (or give the angle) and I’ll give the exact answer.
