Expert Answer
Let the coordinates of third vertice be (x,y).
Length of side by distance formula is given by,AB2=52+12 =26
We have:
(x-3)2 +(y-4)2 = 26 ..(1)
(x+2)2 +(y-3)2 =26 ...(2)
From (1) and (2)
(x-3)2 +(y-4)2 = (x+2)2 +(y-3)2
-5(2x-1)=2y-7
y=-5x+6
Put in (1) and solving for y:
(x-3)2 +(-5x+2)2 =26
26x2 -26x-13=0
x=1.366 x=-0.366
and y=-0.83 or y=7.83
Coordinates can be :(1.366,-0.83) or (-0.366,7.83)
