Answer:
19.105 in if c is the hypotenuse
5.196 in if c is a leg
Step-by-step explanation:
The Pythagorean theorem is used for this.
If c is the hypotenuse, ...
... c² = 13² + 14² = 365
... c = √365 ≈ 19.105 . . . . in
_____
If c is a leg, ...
... 14² = 13² + c²
... c² = 196 -169 = 27
... c = √27 ≈ 5.196 . . . . in
