Question

Q1. From a point on the ground the angles of elevation the bottom and the top of a tower fixed at the top of a 20m high buliding are 45 and 60 respectively. Find the height of the tower.​

Answer 1

Answer:

14.64 m

Step-by-step explanation:

say x be the distance of point pointbfrom base of building .

tan45 = 20/x. = 1

so x = 1

since tower is on top of building,

tan 60 = (20+T)/x = 1+ T/20

T/20 =;root 3 -1

T = 20( root3-1) = 14.64m
