The attached figure represents the explanation of the problem.
The distance between the house and the point B = 7 - 5 = 2
The distance between the house and the cell tower = 4
While the angle B is a right angle.
So, The distance between the house and the cell tower represents the hypotenuse
x and the distance between the house and the cell tower will be the legs
So, x = ![\sqrt{4^2 - 2^2} = \sqrt{16 - 4} =\sqrt{12} =3.464](https://tex.z-dn.net/?f=%5Csqrt%7B4%5E2%20-%202%5E2%7D%20%3D%20%5Csqrt%7B16%20-%204%7D%20%3D%5Csqrt%7B12%7D%20%3D3.464)
The east distance between Town and House = 2 + x = 2 + 3.464 = 5.464 ≈ 5.5 miles
<u>So, The house will be located 5.5 miles east of the town</u>
