Answer:

[tex]AC=16[/tex]

Step-by-step explanation:

This is an isosceles triangle so these 2 sides are equal to each other so to first find x we set them equal then solve

[tex]7x-12=2x+8[/tex]

Add 12 to both sides

[tex]7x=2x+20[/tex]

Subtract 2x on both sides

[tex]5x=20[/tex]

Divide both sides by 5

[tex]x=4[/tex]

Now we need to fill in the value of x to find AC

[tex]7(4)-12\\28-12\\16[/tex]

I hope this helps
