The answer is 24

Using Pythagorean theorem you calculate x = 24

C^2 = A^2 + B^2
30^2 = 18^2 + B^2
900 = 324 + B^2
B^2 = 576
B = square root of 576
B = 24
hazel650

[tex]c {}^{2} - a {}^{2} = b {}^{2} [/tex]

[tex]30 {}^{2} - 8 {}^{2} = b {}^{2} [/tex]

[tex]900 - 64 = b {}^{2} [/tex]

[tex]836 = b {}^{2} [/tex]

[tex] \sqrt{836 } = b[/tex]

[tex]b = 28.914ft[/tex]
