Solution
The correct option is
C
10.4
c
m
Draw a line segment
X
Y
of length
4.8
c
m
From
X
, draw a line at
25
o
from
X
Y
.
From
Y
mark an arc of length of
6.4
c
m
. The arc cuts the line at
25
o
from
X
Y
at
Z
.
These perpendiculars intersect each other at
O
.
Taking
O
as center, draw a circle of radius
O
X
. This circle touches
X
,
Y
and
Z
.
From
Z
draw a line at angle of
40
o
with base
X
Z
. This line cuts the circle at point
W
.
