1.	2) When the length of a shadow of a vertical pole in √3 times of its height the angle ofelevation of the sun’s attitude is ____. a) 15 b) 45 c) 30 d) 60
Answer» 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°

2) When the length of a shadow of a vertical pole in √3 times of its height the angle ofelevation of the sun’s attitude is ____. a) 15 b) 45 c) 30 d) 60

Answer»

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°
