Question

i) A peacock is sitting on the tree and observes its prey on
the ground. It makes an angle of depression of 22° to
catch the prey. The speed of the peacock was observed to
be 10 km/hr and it catches its prey in 1 min 12 seconds.
At what height was the peacock on the tree?
.
anyone?​

Answer 1

theta = 22°

s = 10km/h or 100/36 m/s

t = 1 min 12 seconds or 72 seconds

d = s * time

d = 72 × 100/36

d = 2 × 100

d = 200 m

sin 22° = Perpendicular / Hypotenuse

0.37 = h / d

d × 0.37 = h

h = 0.37 × 200

h = 74

Height at which the peacock is sitting : 74m
