based on the measurements shown on abc ab must be
A:
Concept:
Triangle inequality.
In any triangle with sides AB, BC, CA, AB must satisfy |BC − CA| < AB < BC + CA.
Example:
If BC = 5 and CA = 4, then AB must be between 1 and 9 (i.e., 1 < AB < 9); AB = 6 is valid.
If you share the exact BC and CA values from the diagram, I can give the exact AB.
