C is the circle with the equation x^2 + y^2=1

a) The equation of the tangent to the circle

       x + √3y = 2

b)      

Step-by-step explanation:

Step(i):-

Given the equation of the circle x² +y² =1

Tangent equation of the circle x² +y² =a²  is   xx₁ +yy₁ - a² =0

The tangent equation of the given circle

   xx₁ +yy₁ - 1² =0

This equation passes through the point (

 ⇒   x + √3y = 2

The equation of the tangent to the circle

       x + √3y = 2

Step(ii):-

Slope - intercept form    y = ax +b

                                   √3y = - x + 2
