Answer 2

Step-by-step explanation:

Given Prasad observes a person standing on the ground from a helicopter with  an angle of depression 45 degree. If the helicopter flies at a height of 500 m.  from the ground what is the distance of the person from Prasad.  

• ABC is a right angle triangle given  the helicopter flies at a height of 500 m from the ground. We need to find the distance of the person from Prasad.
• From triangle ABC,
• So tan 45 degree = BC / AC = base / opposite side
•                           = x / 500
• So tan 45 = x/ 500
•         1 = x/500
•      So x = 500 m
