A flag post 10 meters long is fixed on top of a tower. From a point on horizontal ground, the angles of elevation of the top and bottom of the flag post are 40 degrees and 33 degrees respectively. Calculate:
a) The height of the tower
b) The shortest distance from the point on the ground to the top of the flag post

Answer:

Tan33=x/y

y= x/Tan33

Tan40=(10+x)/y

y= (10+x)/Tan40

Therefore

x/Tan33 = (10+x)/Tan40

xTan40-xTan33 =10Tan33

x= 10Tan33/(Tan40-Tan33)

x=34.2m
