A ladder 20 m long is placed against a vertical wall of height 10 metres. Find the distance between the foot of the ladder and the wall and also the inclination of the ladder with the ground.
None of these
Let x = AB = 10m, is the wall
AC is the ladder which is 2x of wall i.e. 20m
sin c = ABAC = 12
C = 30∘
Hence the ladder is inclined 30∘ to the ground
Distance between foot of the ladder and wall = BC = 10√3 m.
A ladder is placed along a wall such that its upper end is resting against a vertical wall. The foot of the ladder is 20 m from the wall and the ladder is making an angle of 60∘ with the ground. Find the height, upto which the ladder reaches. [2 MARKS]
