a electric pole of height 17root 3 m fixed at a comer of a rectangular garden of length 15 m and breath 8m . what is the angle of elevation of the top of the pole when observed form the opposite comer of the pole
Answers
60° is the angle of elevation of the top of the pole when observed form the opposite comer of the pole
Step-by-step explanation:
rectangular garden of length 15 m and breath 8m
Hence Diagonal Length = √15² + 8²
= √225 + 64
= √289
= 17 m
Horizontal Distance between pole & observing point = 17 m
Pole height = 17√3 m
Angle of elevation = α
Tan α = Height of pole / Horizontal Distance between pole & observing point
=> Tan α = 17√3/ 17
=> Tan α = √3
=> α = 60°
60° is the angle of elevation of the top of the pole when observed form the opposite comer of the pole
