**KokkoDeRas**, Monday, September 3, 2012 at 12:52pmto solve this problem we need trigonometry therefore takes the radiant

67°*3,14/180=1,17 rad.= a

point P=50m

height tower H=?

L=hypotenuse of the right triangle LPH

P=Lcos(a)=> (i)L=p/cos(a)

(ii)H=Lsen(a)

(i)+(ii)H=[p/cs(a)]*sn(a)

tan(a)=sn(a)/cs(a)===>H=p*tan(a)=118m
