I NEED HELP SOMEONE PLEASE HELP MEEEE!!!

Answer 1

9.75 ft is the answer

`By \: Pythagoras \: Theorem, \\ \boxed{ {hyotenuse}^(2) = {base}^(2) + {height}^(2) } \\ \\ here \\ hypotenuse = 12ft \\ base = 7 ft\\ height = x\ \\ \\ \ {12}^(2) = {7}^(2) + {x}^(2) \\ \implies144 = 49 + {x}^(2) \\ \implies {x}^(2) = 144 - 49 \\ =95 \\ x = √(95 ) \\ = 9.75 ft\\ \\ \\`
