Answer:
90 m is the height of the tower
Explanation:
The distance between point of 30 degrees and 45 degrees = 30m
Therefore, 15 degrees = 30 m
At 45 degrees the man and tower will make isosceles right angle triangle.
Hence distance from 45 degree point = height of the tower.
= 15 degrees x 3 = height of tower
SInce 15 degrees represent 30 m distance, then replace 15 degrees with 30 m -
= 30 x 3 = Height of tower
= 90 m
