(134 + x) Sqrt [135^2 + (135+ x)^2] - (135 + x) for x = 8970 to 9530 tells that only 83019431 can match as an answer, integer some more compared to other three. Therefore, the objective question only gives one possible matching for integer of side a, although not specified, it would be preferred!

x = 8977

a = 9112

b= 135

c = 9113
