Answer:

The answer is 15 units.

Explanation:

This is the Pythagorean theorem (a^2+b^2=c^2).

We can see that from A to C it is 9 units down. We also know that from C to B it is 12 units long. Using the Pythagorean theorem, we square both numbers, then add them, then take the square root.

9x9=81

12x12=144

144+81=225

The square root of 225=15 *since 15x15=225)*

Therefore A to B is 15 units long!
