A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 265. This question is similar to one that appeared on a GCSE Higher paper (specimen) for 2017. The use of a calculator is allowed.
An arborist sights the top of a tree using a clinometer and reads the angle of elevation to be 29o. Her clinometer is 28 metres from the base of the tree and is on a tripod making it 1.5 metres above ground level.
This diagram is not drawn to scale.
Calculate the full height of the tree.
