Question

the height of a tower is half the height of the flag stuff on it. the angle of elevation of the top of the tower as seen from a point on the ground is 30. find the angle of elevation of the top of the flag stuff as seen from the same point.

Answer 1

angle of elevation of the top of the flag stuff as seen from the same pointing is 60

Answer 2

let the height of the tower be x /2 and of flagstaff be x.

tan 30 = x/2 /b

b = root3 x/2

since ,

p = x

and b = root3x/2

then ,

p/b = x/ root3 x *2

=2/root3

2/root 3 = cosec 30

therefore the angle of elevation is 30 degree

HOPE THIS WOULD BE CORRECT AND HELPFUL.
