A boy 14 m tall, stood 10m away from a tree of height 12 m. Calculate, correct to the nearest degree, the angle of elevation of the top of the tree from the boy's eyes.
The angle of elevation
= Tan θ = \(\frac{opp}{adj}\)
Tan θ = \(\frac{12+14}{10}\)
Tan θ = \(\frac{26}{10}\)
θ = Tan\(^{-1}\)(2.6)
θ ≈ 70º
