AC is 24.25 cm
If true then enter $1$ and if false then enter $0$

In $△ A B E$
$∠ B = 60^{\circ}$ , $A B = 8$
Now,
$cos 60 = \frac{B E}{A B}$
$\frac{1}{2} = \frac{B E}{8}$
$B E = 4$ cm
Also, $B C = 25$
$E C = B C - B E = 25 - 4 = 21$ cm
Now, In $△ A E C$ , $∠ C = 30^{\circ}$
$cos 30 = \frac{E C}{A C}$
$\frac{\sqrt{3}}{2} = \frac{21}{A C}$
$A C = 24.24$ cm
