The height of a vertical tower is to be found by a surveyor. The angle of elevation of the top of the tower from a point on the horizontal ground some distance away is measured as 28.7 degrees. From this point the surveyor moves 21.6 metres directly towards the tower and repeats the measurement. The angle of elevation of the top of the tower from this point is 68.4 degrees. Find the height of the tower.
Can I use SINE rule for this? If so can someone please point out which angles/sides will be what figures. ie.is bc=21.6cm? etc Thankyou The answer given is 15.098cm.
