the length of a string between a kite and a piont on the ground is 90 metres. if the string makes an angle threta with the ground level such that tan threta = 15/8'how high is the kite

tan Q=height/base=15/8

sinQ=heigt of kite from ground/length of string=15/root(15^2+8^2)

                                                                   =15/17

       height of kite from ground=15*90/17

                                           =1350/17 m.
