Using the pythagoras theorem 
side = sqrt (61^2 - 11^2)  =  sqrt 3600  = 60 in Answer
Use the pythagorean theorem (a^2 + b^2 = c^2), 61 is the hypotenuse so it would be C. To solve the problem you would do, (11^2 + b^2 = 61^2). The next step is: (121 + b^2 = 3721). Then: (b^2 = 3600). Finally square root each side to get (b = 60)
