Question

Firefighters ladder of length 30 was kept at a distance of 5 M from a building to reach a window on the building. at what height is a window from the ground? ( pls give ans clearly )

Answer 1

given,

length of ladder = 30m(hypotenues)

distance of ladder from ground = 5m( base)

height of window from ground = ? ( perpendicular)

Acc. to pythagoras theorem:-

(hypotenues) ²=(perpendicular) ²+( base) ²

30²=perp.²+5²

900-25= perp. ²

√875=perp.

=height of window from ground = √875
