answer
The side
b
is
4√2
unit.
Step-by-step explanation:
in right triangle
C=900,a=2,c=6c
is
the side opposite to the right angle, so it is hypotenuse,
a
and
b
are the adjacent sides of the right angle .
We know in right triangle
,a2+b2=
c2∴22+b2=62
or
b2=36−4=32∴
b=√32
or
b=4√2
unit. The side
b is 4√2
unit [Ans]
