The chord of the circle subtend the angles \((4y + 13)^{\circ}\) and \((8y - 35)^{\circ}\) at two points on the same segment of the circle. Calculate the measure of the subtended angles.
Answer:
The value of \(y\) \(=\) \(^{\circ}\)
The theorem used to determine the value is:
The measure of the subtended angles is \(^{\circ}\).
