Question

A flagstaff of height 7 m stands on the top of a tower. The angles subtended by the tower and flagstaff at a point on the ground are 45° and 15° respectively . find the height of the tower.​

Answer 1

Step-by-step explanation:

We can write tan15 as tan(45-30) .

First in Triangle BCD

tan15=BC/DC

tan(45-30)= h/DC

tan (1-1/√3) = h/DC ...........i

Second in Triangle ACD

tan45 = AC/DC

AC = DC

then follow the solution of image
