beks73 [17]

Answer: \bold{10 = \sqrt {\left( {x- 8 } \right)^2 + \left( {y - 9 } \right)^2 }}

Step-by-step explanation:

The coordinates of Point B are unknown: (x, y)

The distance from A to B is 10 units

Then, using the distance formula:

AB = \sqrt {\left( {x- 8 } \right)^2 + \left( {y - 9 } \right)^2 }

Therefore,
