Respuesta :

BC^2 = AB^2 + AC^2

100 = AB^2 + 16
AB^2 = 84

AB = 

Answer:

[tex]9.165 ft\\[/tex]

Step-by-step explanation:

Its a right angles triangle, thus

length of hypotenuse (BC) = [tex]\sqrt{AC^2 + BC^2} \\= \sqrt{16 + BC^2} \\[/tex]

Squaring on both the sides, we get

[tex]BC^2 = 16 + AB^2\\100 = 16 + AB^2\\AB = \sqrt{100 -16} \\AB = \sqrt{84} \\AB = 9.165[/tex]
