Question

A ladder is resting against a wall of height 10m if ladder with the ground at an angle 30 degree then the distance of the foot of ladder from the wall is ​

Answer 1

Answer:

Let AC be the ladder

B be the foot of the wall

Given AB=10 m

Angle of inclination of ladder is 30∘

Let l be the distance of foot of the ladder from the wall

In △ABC,tan30∘=BCAB

⟹31=l10

⟹l=103

So the distance of foot of the ladder from the wall is 103
