Question

Aiko stands 5 m from a tree, At that distance, the angle of elevation from the ground to the top of the tree is 80°. Approximately how tall is the tree? Enter your answer with no measurement rounded to the nearest 10th.

Answer 1

tan α =opposite leg/ adjacent leg = height of tree/distance from the tree
tan 80⁰= height of the tree/5
height of the tree=5*tan 80⁰≈45.0
