Iam stuck with this question.Please anyone help me. An airplane is flying at an altitude of 10,000m.The pilot sees two ships A and B.Ship A is due south of P and 22.5km away(in a direct line).Likewise ship B is due East and 40.8km from P. The height is 10km. Find the distance between the two ships.
Assuming the distances are measured at sea-level, then the altitude of the plane does not affect the distance between the two ships as long as they are navigating both at sea level.
Since they form a right angled triangle with angle P, we can find the distance AB using Pythagoras theorem thus:
