Answer:

AC = 6

Step-by-step explanation:

y is the dimension of the horizontal segment (see the attached image).

The hypotenuses are the same dimension, so:

(x+4)^2=(x/2)^2+y^2

(3x-8)^2=(x/2)^2+y^2

So,

(x+4)^2 = (3x-8)^2

x+4 = 3x-8

x-3x = -8-4

-2x = -12

x = 6

And x is the dimension of the segment AC.

Answer : The length AC is, 6

Step-by-step explanation :

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Thus, [tex]\angle A=\angle C[/tex]

[tex](x+4)=(3x-8)[/tex]

[tex]x+4=3x-8[/tex]

[tex]3x-x=8+4[/tex]

[tex]2x=12[/tex]

[tex]x=6[/tex]

The length AC = x = 6

The length AB = (x + 4) = 6 + 4 = 10

The length AB = (3x - 8) = 3(6) - 8 = 10

Thus, the length AC is, 6
