Case Study 1
36. An injured bird was found on the roof of a building. The building is 15 m
high. A fireman was called to rescue the bird. The fireman used an
adjustable ladder to reach the roof. He placed the ladder in such a way
that the ladder makes an angle of 60 with the ground in order to reach
the roof.

Based on the above information, answer the following questions :
(i) Find the length of the ladder used by the fireman to reach the roof. 1
(ii) Find the distance of the point on the ground at which the ladder
was fixed from the bottom of the building. 1
(iii) In order to avoid skidding, the fireman placed the ladder in such a
way that the bottom of the ladder touches the base of the wall
which is opposite to the building, making an angle of 30 with the
ground.
(a) Draw a neat diagram to represent the above situation and
hence find the width of the road between the building and
the wall. 2
