Question

If the distance from point A to Bis sqrt(72) and point A is (-5,3) coordinates of B?

Answer 1

The distance between two points can be found by the following expression:

`d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}`

Where d is the distance between the points, (x1,y1) and (x2,y2) are the coordinates of the points. In this problem we have the value of d and one of the points so we need to find the coordinates of the other point.

`\begin{gathered} \sqrt[]{72}=\sqrt[]{(x_2+5)^2+(y_2-3_{})^2} \\ 72=(x_2+5)^2+(y_2-3)^2 \end{gathered}`
