A ladder learning against a wall makes an angle of 60° with the ground. If the length of the ladder is 19 m, find the distance of the foot of the ladder from the wall.	Choose the most appropriate option.
A) 9 m  B) 9.5 m  C) 10.5 m  D) 12 m  E) None
Let AB be the wall and BC be the ladder.   Then, &lt; ABC	= 60°   and, BC	= 19 m.;   AC = x metres   AC/BC	= cos 60°   = x / 19   =1 / 2   x= 19/2=
