Question

Karan is swimming in a pool. His friend Arjun is standing outside the pool at a horizontal distance of 1.6m from him. If Arjun's height is 160cm, then what is the angle of elevation of Arjun's head from Karan's eyes?
a) 30° b) 45° c) 60° d) 90°​

Answer 1

Answer:

Angle of elevation = 45°

Step-by-step explanation:

Arjun's height = AB = 160 cm = 1.6 m

Horizontal distance = BC = 1.6 m

Karan is at C.

To find: Angle of elevation = Angle C = ?

In triangle ABC,

AB = opposite side = 1.6 m

BC = Adjacent side = 1.6 cm

tan C = Opposite/adjacent = 1.6/1.6 = 1

Angle of elevation = 45°
