The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.
Step-by-step explanation:
We know that;
We will put the unknown length as √53 to check the solution.
Option 1: a = 6 , b = √53 , c = √91
Option 2: a=√47, b = √53, c = 10
Option 3: a = √19, b=√53, c= √34
Option 4: a=√73, b=√53, c=20
Option 2 satisfies pythagoras theorem.
Therefore;
