Answer:
13cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 12cm
b = 5cm
c = hypotenuse
[tex]12^{2} +5^{2} =c^{2}[/tex]
[tex]144+25=c^{2}[/tex]
[tex]\sqrt{169} =c[/tex]
13 = c
