Answer:
   A.  5
Step-by-step explanation:
The triangle will be a right triangle when the side lengths satisfy the Pythagorean theorem: the sum of the squares of the legs is equal to the square of the hypotenuse.
   (x +1)^2 +x^2 = (√61)^2
   x^2 +2x +1 +x^2 = 61 . . . eliminate parentheses
   2x^2 +2x = 60 . . . . . . .subtract 1, collect terms
   x^2 +x -30 = 0 . . . . . divide by 2, subtract 30
   (x +6)(x -5) = 0 . . . . factor the quadratic
   x = -6 or +5
The solution is x = 5.
_____
Side lengths cannot be negative. Solution values are values of x that make the factors zero. x+6=0 when x=-6, for example.
 
        
             
        
        
        
Answer:
