Question

A man standing at a distance of 100m from a tower observes the top at an angle of 60 degree find the height of the tower ?

Answer 1

first of all write perpendicular upon base equal to cos 60°. in this case you have only the value of base that our distance 100m so fill it in the value of base and leave the value of perpendicular

because you don't have any value for perpendicular. find the vale of cos 60° and fill it on the place of cos 60°. then do cross multiply. and you will know the answer.
