Question

from the top of a 7m high building the angle of elevation of the top of a tower is 60° and the angle of depression of its foot is 45° . find the height of the tower

Answer 1

The height of the tower is 7(√3-1) meters.... pls tell if you need the working.....

Answer 2

7+7√3

distance between building and tower can be calculated by tan45=7/x

x= 7m

now let height of tower will be height of building + y

now tan60= y/7
y=7√3

therefore height of tower will be 7+7√3
