  • a)
    25
  • b)
    25√3
  • c)
    12.5
  • d)
    25√2
Correct answer is option 'A'. Can you explain this answer?

Answers


A point on the ground which is 25 m away from the foot of the tower i. BC= 25 m
Let the height of the tower be x
The angle of elevation of the tower is found to be 45 degree.i.e.∠ACB=45°
In ΔABC
Using trigonometric ratios

Hence the height of the tower is 25 m.

•••hey look , we know the distance from the foot of the tower is 25 m which means , B= 25m and the the angle of elevation is 45 degree •••

we need to find the height of the tower means P

then we know that tan theta = P/B

and tan 45 = P/ 25. ...
then 1= P/25 ...( becoz the value of tan 45 degree is 1)

P = 25 m ans••

•• that's it•••

Let us consider the h of the tower to be AB and the point on the ground is C which is 25 m away from the foot of the tower

tan 45 degree=1
AB/BC=1
AB=BC
AB=25m

hence ,,
is ur ans
