You're on a roll — Here's how to find the values of angles x, y, and m: a) To find angle x: Angle x is POQ. Step 1: Identify the type of triangle OPQ. Since O is the center of the circle, OP and OQ are both radii. Therefore, OPQ is an isosceles triangle with OP = OQ. Step 2: Determine the base angles of OPQ. In an isosceles triangle, the angles opposite the equal sides are equal. So, OQP = OPQ. Given OPQ = 24^, thus OQP = 24^. Step 3: Use the sum of angles in a triangle. The sum of angles in OPQ is 180^. x + OPQ + OQP = 180^ x + 24^ + 24^ = 180^ x + 48^ = 180^ Step 4: Solve for x. x = 180^ - 48^ x = 132^ Angle x is 132^. b) To find angle y: Angle y is PTQ. Step 1: Relate the angle at the center to the angle at the circumference. Angle x ( POQ) is the angle subtended by arc PQ at the center. Angle y ( PTQ) is the angle subtended by the same arc PQ at the circumference. The angle at the center is twice the angle at the circumference. POQ = 2 × PTQ x = 2y Step 2: Substitute the value of x and solve for y. 132^ = 2y y = (132^)/(2) y = 66^ Angle y is 66^. c) To find angle m: Angle m is SQR. Step 1: Apply the Alternate Segment Theorem. SR is a tangent to the circle at Q. SQR is the angle between the tangent SR and the chord PQ. According to the Alternate Segment Theorem, this angle is equal to the angle in the alternate segment, which is PTQ (angle y). m = PTQ m = y Step 2: Substitute the value of y. m = 66^ Angle m is 66^.
