If two sides of the right angle are equal then it is a isoceles angle
Let each equal side be a 
Then according to the Greek philosopher Pythagoras ;
⇒50 = 2a²
⇒ a² = 50/2
⇒ a² = √25
⇒ a = 5 units                                                        Ans.
Hence, the length of Each side of the right triangle is 5 units     Ans.
I hope my answer satisfies you , if it really does please mark my answer as the best .
