Answer:
x = 4, y = 6, z = 7
Step-by-step explanation:
Given that for a triangle FGH, lines s, t and u are perpendicular bisectors.
They concur at the point J.
We know that the point of concurrence of perpendicular bisectors is the circmcenttre of the triangle. Hence we will have J equidistant from the three vertices. In other words,
JG = JH=JF
[tex]2x+2 = 2y-2 = 10\\x =4, y = 6[/tex]
Now to find Z we make use of HI.
[tex]JF =HI = 2z-4\\i.e. 10 = 2z-4\\z = 7[/tex]
So option a is right answer
x = 4, y = 6, z = 7
