the horizontal distance between the two towers is 75 m and angle of depression of the top of the 1st tower as seen from top of 2nd ,which is 160m high ,is 45°.Find the height of the 1st tower.
second tower-160 m
distance - 74 m
when we draw an angle of depression to the top of the first tower from the second tower.we get the angles, 45,45,90.as in the ratio 1:1:√2.as we get the height if the first tower,160-75=85m.
is it right?
