Surveying In order to locate the position (P) of a sounding boat, the angles APB & BPC subtended at P by three points A, B and C on the shore were measured with a sextant and found to be 28º 42’ 40” and 30º 28’ 20” respectively, the point B & P being on opposite of AC. The length of AB & BC scaled from a map were 662 m and 4662 m respectively, and the angle ABC was 60º 50’ 40”. Carry out all the necessary calculations to compute the distances PA, PB and PC.
