City Guilds Model Questions Vol1 2025 Engineering Question 30
Practice objective / multiple choice question 30 from the 2025 City Guilds Model Questions Vol1 Engineering examination.
A surveyor wishes to determine the height of a cliff. From a point on level ground, the angle of elevation to the top of a vertical staff of length \(1.5\ \text{m}\) placed on the ground is measured as \(45^{\circ}\). The angle of elevation to the top of the cliff from the same point is measured as \(60^{\circ}\). The horizontal distance from the observer to the foot of the staff is measured as \(d\) metres, with a possible error of \(\pm0.05\) m. Using these data, calculate the maximum possible error in the computed height of the cliff (in metres), giving your answer to two decimal places.
