The distance covered by boat is 18.44 miles.

Step-by-step explanation:

Use the given information to draw a figure.

           (Alternate interior angles)

    (Supplementary angles)

According to angle sum property of a triangle, the sum of interior angles is 180 degree.

Since two angles are same, therefore ABC is isosceles triangle.

Use Law of Sine:

The perimeter of triangle ABC is

Therefore the distance covered by boat is 18.44 miles.
