Practice essay / theory question 8 from the 2020 Bece Model Questions Vol1 Mathematics examination. This question covers Approximation, Trigonometry, Linear interpolation, Mensuration .
A tree casts a shadow that is 12.5 metres long. The angle of elevation of the sun is measured with a clinometer that only gives readings at 30° and 35°. The recorded reading is 33°, which must be estimated by linear interpolation between the two known values. Given: - tan 30° = 0.577 - tan 35° = 0.700 Using linear interpolation, estimate tan 33° and then determine the height of the tree, giving your final answer to the nearest metre.
