**Reiny**, Saturday, December 28, 2013 at 10:31amI assume you made a sketch.

On mine I let the distance between tower and cliff be x m

then tan60° = 100/x

x = 100/tan60°

In my smaller right-angled triangle at the top of my diagram ,

let the difference between height of tower and height of cliff be h

then tan 30 = h/x

h = xtan30

= (100/tan60)tan30

then height of tower = 100 - h

I will let you do all that button-pushing,

let me know what you got
