Hello student,
The lengths of medians of triangle sa,sb,sc are given by
sa=\sqrt{\frac{2b^{2}+2c^{2}-a^{2}}{4}}
sb=\sqrt{\frac{2c^{2}+2a^{2}-b^{2}}{4}}
sc=\sqrt{\frac{2a^{2}+2b^{2}-c^{2}}{4}}
But in a right angled triangle\angle B=90(since given c as hypotenuese)
also c2=a2+b2
so sc=c/2
so (sa+sc)/sc=1+(sa/sc)=1+(\sqrt{4b^{2}+a^{2}}/c)
Thanks and Regards
