I need help finding the answer to this

Answer:
50 in, 48 in, 14 in.
Step-by-step explanation:
If it's a right triangle then it will fit the Pythagoras theorem
c^2 = a^2 + b^2 where c is the hypotenuse.
50^2 = 2500
48^2 = 2304
14^2 = 196
2304 + 196 = 2500.
So its the second choice.
Hope this helps.
