Q12 of 68 Page 9

The length of the shadow of a high bamboo tree is 3m, then what will be the angle of elevation of the top of the bamboo tree at the end of the shadow.

Drawing the given diagram so that we get a better understanding of the problem,



We have to find the angle of elevation of the end of bamboo from the end of the shadow with the horizontal as the reference line from which the angle is measured.


We know that from trigonometric ratios that,



Therefore, using this ratio in this problem,





Θ =30°


Therefore, the angle of elevation is 30°.
