A) Work out the value of x and give a reason for your answer.
53°
Lo
b) Work out the value of y and give
a reason for your answer.

x = 106°

y = 127°

Step-by-step explanation:

x = 2* 53° = 106°

(Measure of the angle subtended on the center of the circle is twice the measure of inscribed angle)

y = 1/2 ( 360° - 106°)

(By inscribed angle theorem)

y = 1/2 *254°

y = 127°
