Question

Equation of two sides of a triangle are the lines $7x+3y-20=0$ and $3x+7y-20=0$ and the third such passes through the point $(-3,3)$, then the equation of the third side can be

• A. $x+y=0$
• B. $x-y+6=0$
• C. $x+3=0$
• D. $y=3$

Answer 1

The correct option is A $x+y=0$

Equation of the line passing through the point $(-3,3)$ myst satisfy the equation

Required equation of the line is $x+y=0=>-3+3=0$

Required line is $x+y=0$
