Question

A ladder of 12 cm length touhes a wall at height of 6m. find how far is the foot of the ladder from the building, if the ladder inclined an angle​

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
