					                   So the question ask to find the value of x that makes the triangle above a right triangle and the best way to answer this is by doing the Pythagorean formula of c^2=a^2+b^2 and the answer would be  X=31. I hope you are satisfied with my answer 
					                
					                
					             6 square root of 10
a^2+b^2=c^2
a=x
b=x+1
c=square root of 61
x^2+x^2+1=61
x^4=60
x=6 square root of 10
