Answer:

BC = 24 in

Step-by-step explanation:

since AB is a tangent to the circle then ∠ BAC = 90°

using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{12}{BC}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

BC = 24
