18. The shadow of a tower standing on a level ground is found to be
30 m longer when e sun's altitude is 30°, an when it was 60°.
Find e height of e tower. [Take 3 =1.732.]

20. A aeroplane is flying at some height. The pilot s s e
airp t making an angle of 30° wi e airp t . Find e
height of e aeroplane at at instant if e plane had to
travel 165m heading towards airp t.

21. A aeroplane is flying at some height. The pilot s s e
airp t making an angle of 30° wi e airp t . Find e
height of e aeroplane at at instant if e plane had to
travel 165m heading towards airp t.

22. The angle of elevation of e top of a hi at e foot of a tower
is 60° and e angle of depression from e top of e tower
to e foot of e hi is 30°. If e tower is 50 m high, find
e height of e hi .

24. If a tower 30 m high, casts a shadow 10/3 m
long on e ground, en what is e angle of
elevation of e sun?
