Answer:

The equations are

Step-by-step explanation:

Given Two sides of isosceles triangle are given by the equations 7x-y+3=0and x+y-3=0 and the third side passes through the points (1,10).

We have to find the equation of the third side.

Slope intercept form is

y=mx+c

Slope of 7x-y+3=0 is 7

Slope of x+y-3=0 is -1

Let slope of third line i.e BC is m

Since ΔABC is isosceles therefore angle on the bases are equal.

⇒  

As,  

⇒  

⇒  

and  

and  

and  

not possible

Let m=-3, then equation of third side is

⇒  

Let , then equation of third side is
