@MissSosa length of which side?

anonymous · Answer

Of FE, sorry about that.

ash2326 · Answer

We have
ΔABC ≅ ΔEDF
Using CPCTC
FE=CA
so just find AC's length, can you find that?

anonymous · Answer

I don't know how? Tell me how, and than I can.

ash2326 · Answer

You have to find AC
A's coordinates = (0. 1)
C's coordinates= (3, 2)
so 
$$AC=\sqrt{(3-0)^2+(2-1)^2}$$
Calculate AC from here, FE=AC!!

okay the triangle is a right angled triangle. therefore  $$(bc)^{2}+(ab)^{2}=(ac) ^{2}$$
according to pythogoras equation.
therefore value of ac is $$\sqrt{10}$$
which is equal to
$$3.16\approx3.2$$
AC is equal to FE
