AC = 12 cm.
Step-by-step explanation:
In a 30-60-90 triangle,
side opposite to 30° = 1/2 of hypotenuse and
side opposite to 60° = (√3/2) of hypotenuse.
Here, BC is the side opposite to 30°
therefore, BC = (1/2) AC
AC = 2BC
AC = 2 × 6 = 12 cm.
Hence, the answer.

AC=12cm
Step-by-step explanation:
In a 30-60-90 triangle,
side opposite to 30° = 1/2 of hypotenuse and
