is (60+ 20√3 )m wide. At a point O on the road between the pillars, the angle
of elevation of the tops of the pillars are 60degree
and 45degree
(a) The height of the pillar is

(i) 50m (ii) 30m (iii) 60m (iv) 20√3m

(b)The distance from the point O to the pillar CD is

(i) 60m (ii) 20√3 m (iii) 20m (iv) 60√3m

(c) Find the value of tan450
+ sin600
(i) 2 (ii) 3
2
(iii) 1 + √3
2

(iv) 1 −
√3
2

(d) The distance from the point O to the pillar AB is
(i)60m (ii) 20 m (iii) 20√3m (iv) 60√3m
(e) The distance from the point O to the top of the pillar AB

(i)40m (ii) 60 m (iii) 60√2m (iv) none of these
