Eliminate the parameter

Step-by-step explanation:

In the question given correct parameter is -  2)  

Method -

   ........................(1)

 ..........................(2)

Let's solve the equation 1,

⇒  

⇒            

      Here we got the y parameter as

So the option no .2 is the correct option 2)

a² + b²= c²

24² + 7² = c²

c= 25

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
