RT leg and perimeter

Calculate the length of the sides of a right triangle ABC with hypotenuse c when the length of a leg a= 84 and perimeter of the triangle o = 269.

Correct result:

a =  84
b =  73.4297
c =  111.5703


a=84 o=269
a2+b2=c2 a+b+c=o  7056=c2b2 b+c=185  7056=c2(185c)2 7056=c2(18522185c+c2) 7056=1852+370c 41281=370c c=111.57 b=185c=73.4297
