A 10 metre, long ladder is placed against a wall. It is inclined at angle of 30C to the ground. The distance of the foot of the ladder from the wall is
This can be represented in diagrammatic form as,
Â
Hence, by 30-60-90 theorem
Side opposite to 60 degree angle = $$\sqrt{3}$$/2 *hypotenuse = $$\sqrt{3}$$/2 *10 = 8.66 m
Therefore, the correct option is option C.
