A, B and C are three known control stations and P is the position of a sounding vessel which is to be located. If AC = 6925.50m and AB = 6708.40m, angle BAC = 112°45'25", angle BPA = 25°32'40", angle APC = 45°35'50", determine the distance AP if A is nearer to P than B and C.
To test its line of sight adjustment, a level is set up near C (elev. 193.436 m) and then near D. Rod readings listed in the order taken are C = 1.315 m, D = 0.848 m, D = 1.296 m, and C = 1.767 m. Compute the elevation of D, and the reading required on C to adjust the instrument.
A transit with a stadia constant equal to 0.30 is used to determine the horizontal distance betweeen points B and C, with a stadia intercept reading of 1.75 m, the distance BC is equal to 185.87m. Using the same instrument, it was used to determine the difference in elevation between B and D having a stadia intercept reading of 2.42 m at D at a vertical angle of (+) 6-30-00.

A, C and D are three triangulation shore signals whose positions were determined by the angle ACD = 150° and the sides AC is 810m and CD = 720m. A sounding at B was taken from the boat and the angle ABC = 39°30' and angle CBD = 33°30' were measured simultaneously by sextants from the boat to the three signals on the shore. Find the angle CDB.
