Survey Transit
Science/Math Question?
A surveying party wishes to find the distance between a point (A) on one side of a stream and a point (B) on the opposite Bank. The surveyor sets the transit over point A and backsights on point B. He then turns his transit through a 90 degree angle and foresights toward point C. The party sets point C at any convienient distance from A and, using a Steel Tape, measures and records a distance of 801 feet. The surveyor sets the transit over point C, backsights on A, and turns the telescope to point B. He measures the angle between his sighting on A and his sighting on B and finds it is 28 degrees. With this information, what is the distance from point A to point B?
tan(theta)=y/x
from the problem,
theta=28
x=801
so:
y=801 tan(28)
