Answer 1

Answer:

a similar question

Step-by-step explanation:

Height of building = 60 m

Angle of elevation = 30 degrees  

Depression of height = 60 degrees

Height of building is denoted as AB and height of watchtower is denoted as DE.  

60/root3 = 20 root3

Distance between building and watchtower = 20 root3

To find difference in height of the buildings:

1/root3 x h/20 root3

h = 20 m

Height, h = 20 m
