Medians in right triangle

It is given a right triangle, angle C is 90 degrees. I know it medians t1 = 8 cm and median t2 = 12 cm. .. How to calculate the length of the sides?

Correct result:

a =  11.6847 cm
b =  5.465 cm
c =  12.8996 cm


t1=8 cm t2=12 cm  t12=x2+(2y)2 t22=y2+(2x)2  x2=t124y2  y=4 t12t2215=4 82122152.7325 cm x=t124 y2=824 2.732525.8424 cm  a=2 x=2 5.8424=11.6847 cm
b=2 y=2 2.7325=5.465 cm
a2+b2=c2  c=a2+b2=11.68472+5.4652=12.8996 cm
