Question

a man standing 10 metres away from the foot of a tree sees its top at an elevation of 40 °.His height is 1.7 metres.What is the length of the tree?​

Answer 1

Answer:

Let the height of tower be h 

Let height of hill be x 

tan60o=40x−1.75⇒3=40x−1.75

403=x−1.75

∴, height of hill  x=71.03 m

tan50o=40x−h−1.75

1.19=4071.03−h−1.75

47.67=71.03−h−1.75

Height of towerh=21.1 m
