Answer:

(5,6) , (5,-2)

Step-by-step explanation:

Let the required point be P(5,y).

Its distance from (2,2) is 5 units.

So, [tex](5-2)^{2}[/tex] + [tex](y-2)^{2}[/tex] = 25.

So, [tex]3^{2}[/tex] +  [tex](y-2)^{2}[/tex] = 25.

  9 +  [tex](y-2)^{2}[/tex] = 25.

   [tex](y-2)^{2}[/tex] = 16

    Two cases are possible for now

case 1 : y-2 = 4 .

            y = 6

required point will be (5,6)

case 2 : y - 2 = -4.

              y = -2.

required point will be (5,-2).

Two points are possible : (5,6) , (5,-2).
