Question

Suresh places a mirror on level ground to determine the height of pole (with traffic light fired on it). He stands at a certain distance so that he can see the top of the pole reflected from the mirror. Suresh’s eye level is 3 m above the ground. The distance of Suresh and the pole from the mirror are 3.6 m and 12 m respectively, then
a) Which criteria of similarity is applicable to similar triangle?
SSA b) ASA c) SSS d) AA
b) What is the height of the pole?
12 m b) 16 m c) 10 m d) 8 m
c) The angle made by Suresh’s eye is i, which of the following is the correct relation?
tani = 5/6 b) tani = 6/5 c) tani = 3/5 tani = 5/3
Now Suresh move behind such that the distance between pole and the Suresh is 26 meters. He place mirror between him and pole to see the reflection of light in right position.
d) What is the distance between mirror and Suresh?
14 m b) 6 m c) 10 m d) 8 m
e) What is the distance between mirror and the pole?
18 m b) 16 m c) 24 m d) 20 m
