Mathematics

well, the triangle is an isosceles, so it twin sides, and the twin sides make twin angles, as we see by the tickmarks on A and C, meaning AB = BC.

\bf x+4=3x-8\implies 4=2x-8\implies 12=2x\implies \cfrac{12}{2}=x\implies 6=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ AC\implies x+4\implies 6+4\implies 10

Answer : The length of AC is, 6

Step-by-step explanation :

As we know that when the two angles in a triangle are equal then the there adjacent sides are also equal.

That means,

∠A = ∠C

So,

Side AB = Side BC

x + 4 = 3x -8

3x - x = 8 + 4

2x = 12

x = 6

The values of 'x' is 6

So, the length of AC = x = 6

4

9

16

25

36

49

64

81

100

Step-by-step explanation:

1 = 1²

4 = 2 x 2 = 2²

9 = 3 x 3 = 3²

16 = 4 x 4 = 4²

25 = 5 x 5 = 5²

36 = 6 x 6 = 6²

49 = 7 x 7 = 7²

64 = 8 x 8 = 8²

81 = 9 x 9 = 9²

100 = 10 x 10 = 10²
