A submarine travels N45 W 16 miles. It then turns a course of 216 measured clockwise off of due north and travels until it is due west of its original position. How far is it from where it started?

19.5 miles

Step-by-step explanation:

The question is represented in the image attached.

∠A = 45°, ∠B = 45° + (216° - 180°) = 81°

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

45° + 81° + ∠C = 180°

126 + ∠C = 180

∠C = 180 - 126

∠C = 54°

The sine rule states that for a triangle with sides a, b, c and their corresponding opposite angles A, B and C. The following rule holds:

b = length of beginning of submarine to end point. Using sine rule:
