Challenge Problems
Push your limits with challenges.
Question 1
A building stands at the top of a hill 150m away. If the vertical angle to its peak is 45 degrees, what is the height of the building? Assume your instrument is 1.5m high.
💡 Hint: Be mindful of the distances and angle used for calculations.
Question 2
Two surveyors set positions A and B on flat ground with a distance of 50m between them. From A, they measure an angle of elevation of 40 degrees to the top of a hill; from B, they measure 30 degrees. Calculate the height of the hill above BM, considering the base elevation of 20m.
💡 Hint: Use trigonometric identities to relate angles and distances for finding heights.
