Step-by-step explanation:
In any 30-60-90 triangles, the sides are in ratio , where
is the side opposite to the 30 degree angle and
is the hypotenuse of the triangle.
In the given diagram, the hypotenuse is marked as 12 miles. Therefore, the side opposite to the 30 degree angle must be miles. The final leg,
, must then represent the
part of our ratio, hence
