If AC = 15 centimeters, and BC = 12 centimeters, which does AB equal?

What kind of figure is this?

a right triangle

Is this what it looks like?
A




___________B
C 
yes

Use the Pythagorean Theorem.
a^2 + b^2 = c^2
15^2 + 12^2 = c^2
225 + 144 = c^2
369 = c^2
19.21 = c
ab = 19.21 cm 
thank you

You're welcome.
