**Reiny**, Monday, June 10, 2013 at 8:29pmdid you make a sketch?

I have , top of tower -- P , bottom of tower Q

closer point A

farther point B

In triangle PBA

angle B = 29°5'

angle BAP = 142°55'

angle BPA = 8°

AB = 120

by sine law:

PA/sin 29°5' = 120/sin 8°

PA = 419.1165

now triangle APQ is right-angled

use

sin 37°5' = PQ/PA

you finish it
