b + c + 6 = 15

b = 9 - c

c2 = 62 + (9 - c)2

c = 6.5

\(6+b+c=15\)

\(36+b^2=c^2\)

\(c=\sqrt(36+b^2)\) that is 36 and b^2 in the square root

\(c=6+b\)

\(6+b+6+b=15\)

\(12+2b=15\)

\(2b=3\)

\(b=1.5\)

\(c=15-7.5\)

\(c=7.5\)

Someone check my work plz maybe it is wrong and guest got a different answer so idk whose is right
