Question

The angle of elevation of the top of a tower standing on a horizontal plane from a point A is a. After walking a distance d towards the foot of the tower, the angle of elevation is found to be B. Then the height of the tower is

• A. \(\frac{d}{tan\,a-tan\,ẞ}\)
• B. \(d(cot\,a-cot\,B)\)
• C. \(\frac{d}{cot\,a-cot\,ẞ}\)
• D. \(d(tan\,a-tan\,ẞ)\)

Answer 1

The Correct Option is C

The correct option is (C): \(\frac{d}{cot\,a-cot\,ẞ}\)
