In circle B above, the circumference is 72 mm and the length of minor arc CA is 6 mm. What is the measure of angle CKA?

30 degrees

Step-by-step explanation:

Total circumference of circle B = 72 mm

The circumference of 72 mm corresponds to a total subtended angle of 360 degrees.

Length of the minor arc CA = 6mm

Let the angle subtended by CA at the center of the circle = x degrees.

Then

Hence the angle subtended by the arc CA at the center is 30 degrees.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
