Answer:
a = 26 or 21.82
Explanation:
If 'a' is the hypotenuse, then ...
a² = b² +c²
a² = 24² +10² = 576 +100 = 676
a = √676 = 26 . . . if 'a' is the hypotenuse
__
If 'a' is the long side, then ...
b² = c² + a²
b² -c² = a² = 24² -10² = 576 -100 = 476
a = √476 ≈ 21.82 . . . if 'a' is the long leg

Comment on the question
The problem statement doesn't tell us what side of the triangle is labeled 'a'. There are two possibilities. An answer has been provided for each. Use the one that applies to the figure you are given.
