Medians and sides

Triangle ABC in the plane Oxy; are the coordinates of the points:
A = 2.7
B = -4.3

Try to calculate the lengths of all medians and all sides.

Correct answer:

a =  10.7703
b =  8.9443
c =  7.2111
t1 =  6.0828
t2 =  8
t3 =  9.2195

Step-by-step explanation:

a=BC a=(46)2+(3(1))2=2 29=10.7703
b=AC b=(26)2+(7(1))2=4 5=8.9443
c=AB c=(2(4))2+(73)2=2 13=7.2111
