on
placing
it
against
a
wall
at
a
distance


‘q’
meters
from
the
foot
of
ladder.
Find


the
distance
(q)
of
the
foot
of
the
ladder


from
the
wall.​

Answer 1

Answer:

225-144=169==>169^1/2=13metres

q=13 metres

Step-by-step explanation:

The ladder forms a right angled triangle with the wall. The height of the ladder forms the hypotenuse and the height of window is the perpendicular. The distance forms the base, which is q.

Pythagoras theorem is used to solve the problem for q.

q^2+12^2=15^2
