Hello, Ilsa!

Three points have coordinates: .

If where , calculate the value of and.

given that and that the area ofCode:| (x,y) (7,6) | P o * B | o * * | o * * | * o * | * o | * * o | * * o | * * - - * - - - - - - - - - - - * - - - - - - (0,0) (5,0) O A

Since is equidistant from and

. . lies on the perpendicular bisector of

. . which has the equation: .

Code:| P | o (x,y) | * :* | * : * | * : * | * :y * | * : * | * : * O| * : * A - - * - - - - - - - + - - - * - - (0,0) (5,0)

The area of is 10 units

Its base is 5 and its height is .

. .

Hence: .

Therefore: .
