Question

A(-3, -4), B(-5, 0), C(3, 0) are the vertices of ∆ABC. Find the coordinates of circumcentre of ∆ABC​

Answer 1

Answer:

Consider the given equations,

5x−y=5 ………(1)

3x−y=3 ………(2)

solving (1)

5x−y=5

5x=5+y

y=5x−5

so, If put x=0, then y=−5 put y=0, then x=1

then, (0,−5) is a solution

and (1,0) is a solution.

Solving (2)

3x−y=3

y=3x−3

So, If put x=0, y=−3

put y=0, x=1

then, (0,−3) is a solution, and (1,0) is a solution.

We will plot both equation on the graph.

Therefore, ΔABC is the required triangle.
