The vertical circle readings shown below were taken to two stations A and B using a 01" reading total station correctly set-up and levelled above a station Y. The vertical circle of the instrument used was graduated such that readings less than 90° were obtained for angles of elevation with the total station in the face left position. Point Sighted A FL Vertical Circle Reading 91° 34' 26" FR Vertical Circle Reading 268° 25' 48" The vertical angle to station A is: A. В. +01°34'26" -01°34'19" С. D. -01°34'26" +01°34'19"

Calculate the vertical index difference and vertical angle in Tab.
Complete answer
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.

Ex-2-: In a levelling process the readings were recorded as following: (1.349, 1.723, 1.522, 1.634, 1.542, 1.773, 1.829 m). If the Level instrument was relocated after the fourth reading and the level of the fourth point was (30 m). Calculate the elevations of the other points and do check your calculations.
