Question 4: Step 1: Identify the properties of OQR. O is the center of the circle, so OQ and OR are radii. Therefore, OQ = OR, which means OQR is an isosceles triangle. In an isosceles triangle, the base angles are equal: OQR = ORQ. From the diagram, QOR = x and ORQ = y. The problem states "If TQ = TR and x = 120^". Based on the diagram, x refers to the central angle QOR. Step 2: Calculate the value of y. The sum of angles in $
