Answer:
A. 13 ft.
Step-by-step explanation:
To solve this question, you will need to use the Pythagorean Theorem. In the Pythagorean Theorem, [tex]a^{2} +b^{2} = c^2[/tex].
a = 5
b = 12
c = c
[tex]5^2 + 12^2 = c^2[/tex]
[tex]c^2 = 5^2 + 12^2[/tex]
[tex]c^2[/tex] = 25 + 144
[tex]c^2[/tex] = 169
[tex]\sqrt{c^2}[/tex] = [tex]\sqrt{169}[/tex]
c = 13
So, your answer is A. 13 ft.
A shortcut, though, is just to memorize a few basic Pythagorean triples, as listed below.
Hope this helps!
