​

Answer 1

Answer:

sorry

I can't find the answer

Answer 2

Answer:

Given A(7, -36) B(7,20) C(-8,0)

a = BC =

(−8−7)

2

+(0−20)

2

=

400+625

=25

b = CA =

(−8−7)

2

+(0+36)

2

=39

c = AB =

(7−7)

2

+((20+36)

2

)

=56

a = 25, b = 39, c = 56

In center =(

25×7+36×7+56×8

),(

25+39+56

25×−36+39×20+56×0

)

=(
