A) work out the value of X and give a reason for your answer. b) work out the value of y and give a reason for your answer.

a). x = 106°

b). y = 127°

Step-by-step explanation:

a). Since, "angle subtended by an arc at the center is twice the angle subtended at the circumference"

  x° = 2(53°)

  x = 106°

b). Since, "Opposite angles of a cyclic quadrilateral are supplementary angles"

  Therefore, y° + 53° = 180°

   y = 180°- 53°

   y = 127°

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
