Answer:

AC = 6

Step-by-step explanation:

given ∠A = ∠C then triangle is isosceles with BC = AB, hence

3x - 8 = x + 4 ( subtract x from both sides )

2x - 8 = 4 ( add 8 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

⇒ AC = x = 6

So.. let's say ∡AGB and ∡BGC are say "a" units wide, and ∡CGD and ∡DGE are "b" units wide

notice the picture below

all angles added up together, will make up just a flat line, or 180°

now, notice in the picture, the ∡BGD is really just " a + b " wide, notice the green angle in the picture of ∡BGD, well, we know what a + b is
