Challenge Problems
Push your limits with challenges.
Question 1
You are standing 50 meters from a building. The vertical angle to the top is measured at 35 degrees. If your instrument is 1.8 meters above the BM, calculate the height of the building.
💡 Hint: First, find the height above the instrument axis.
Question 2
If the instrument is set up at two points 100 meters apart on level ground, measuring the heights of two towers with angles of 20° and 25° from each point, how do you calculate the height of the towers?
💡 Hint: You will need to consider the different positions and angles when calculating each height.
