surveyor wishes to measure the distance across a stream. He sets up his transit at a point C on the bank of the stream, and sights on a point B on the other bank directly opposite him. Then he turns the transit through a right angle, and measures off a distance of 100 feet to a point A. He moves the transit to A, and measures the angle CAB, which he finds to be 50°. How wide is the stream?

To determine the horizontal distance between Q and R, a tacheometer was used and was placed at P. The stadia intercepts for Q and R were recorded to be 0.320 m and 0.210 m respectively. Calculate the horizontal distance between Q and R if the angle QPR is equal to 61° 30' 30". Take stadia multiplication constant as 100 and the stadia addition constant as 0.10 m.
Situation 01. In a survey within the catchment area of a lake, Thiessen polygons were established by setting up a transit at Point Z, which is the inner portion of a four-sided lake MNOP. The readings are as follow: BEARING N 40°30' W N 38° E S 70° E | S 60° 15' W | 695.10km RAINFALL, ft DISTANCE 420.35km LINE ZM 0.211 ZN 530.15km 0.26 zo 480.75km 0.239 ZP If the rainfall from the area of bounded by ZMP is the Arithmetic Mean of the other rainfalls, compute the average precipitation (in cm) by Thiessen Polygon Method.
