We can know from the pic
2x+38=90
so, x=26
Answer: a. Radius of circle =
b. The equation of this circle :
Step-by-step explanation:
Given : Center of the circle = (3,10)
Circle is passing through (12,12).
a. To find the radius we apply distance formula (∵ Radius is the distance from center to any point ion the circle.)
Radius of circle =
Radius of circle =
i.e. Radius of circle =
b. Equation of a circle = , where (h,k)=Center and r=radius of the circle.
Put the values of (h,k)= (3,10) and r= , we get
∴ The equation of this circle :
