The Pythagorean Theorem states that the sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse. Use the Pythagorean Theorem formula
[tex]A^{2}[/tex] + [tex]B^{2}[/tex] (14 Ft.) =[tex]C^{2}[/tex] (13Ft.)
[tex]A^{2}[/tex] + (13)(13) = (14)(14)
[tex]A^{2}[/tex] + 169 = 196
[tex]A^{2}[/tex] = 196-169
[tex]A^{2}[/tex] = 27
