Question

2) When the length of a shadow of a vertical pole in √3 times of its height the angle of

elevation of the sun’s attitude is ____.

a) 15 b) 45 c) 30 d) 60​

Answer 1

Answer:

c) 30°

Explanation:

AB=height of vertical pole

CB=length of vertical pole

according to question

the length of a shadow of a vertical pole in √3 times of its height

let height of vertical pole is h so length of vertical pole is h√3

In ∆ABC

tanC=AB/CB

tanC=h/h√3

tanC=1/√3

C=30°
