Question

the radar determines that it is 2, 650 meters away.
a.) By what angle did the ship's bearing from corregidor change?
b.) How far did the Ship travel between the two observation points?

Answer 1

at CPA, the distance is 90 degrees frm the course.

So you have right angle triangle.

angle=arccos(2400/2650)

distancetraveled= 2650*sinAngle

Answer 2
