PLEASE HELP FAST!
what is the length of segment AB?

Answer:
13
Step-by-step explanation:
Use Pythagorean Theorem ([tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]):
side a = 5
side b = 12
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
= [tex]5^{2}[/tex] + [tex]12^{2}[/tex] = 169
[tex]\sqrt{169}[/tex] = 13
I hope this helps :)
