a
very


important
and
useful
property
of
rightangled
triangles.
That
property
is
named


Pythagoras
property.
As
per
this


property,
in
a
right
triangle
square
of


hypotenuse
is
equal
to
the
sum
of
squares


of
other

sides.


A
15
meters
long
ladder
reached
a


window
12
meters
high
from
the
ground


on
placing
it
against
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:

as ladder is 15 m so hypotenuse is 15 m and length of wall is 12 m and let distance from wall be X

so 15² = 12² + X² (pythagoras property)

225 = 144 +X²

225 - 144 = X²

81 = X²

9 = X
