Question

pls solve this question in easy way
find the circumcenter of triangle whose sides are x+y+2,5x-y-2,x-2y+5​

Answer 1

Answer:

A

3x−y−5=0

⇒y=3x−5

B

x+2y−4=0

y=2−1x+2

C

5x+3y+1=0

y=3−5x−31

D

3x−5=2−1x+2

⇒D(2,1)

E

3x−5=3−5x−31

⇒E(1,−2)

F

2−1x+2=3−5x−31

⇒F(−2,3)

Use these point to make a circle.

D=(2−h)2+(1−k)2=r2

E=(1−h)2+(−2−k)2=r
