Step 1: Apply the Alternate Segment Theorem. The Alternate Segment Theorem states that the angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment. • The tangent is PQ and the chord is AT. The angle between them is PTA = 60^. Therefore, the angle in the alternate segment, ABT, is equal to PTA. ABT = PTA = 60^ • The tangent is PQ and the chord is BT. The angle in the alternate segment is BAT = 44^. Therefore, the angle between the tangent and the chord, QTB, is equal to BAT. QTB = BAT = 44^ Step 2: Use the information that TC bisects BTQ. Given that TC bisects BTQ, it means that BTC = CTQ. Since BTQ = QTB = 44^: BTC = (1)/(2) × BTQ BTC = (1)/(2) × 44^ BTC = 22^ Step 3: Apply the Exterior Angle Theorem to BTC. The line ABC is a straight line. This means that ABT is an exterior angle to BTC at vertex B. The Exterior Angle Theorem states that an exterior angle of a triangle is equal to the sum of the two opposite interior angles. For BTC, the exterior angle at B is ABT, and the opposite interior angles are BTC and BCT. ABT = BTC + BCT Substitute the values we found: 60^ = 22^ + BCT Step 4: Solve for BCT. Subtract 22^ from both sides: BCT = 60^ - 22^ BCT = 38^ Since BCT is the same as ACT, we have: ACT = 38^ The final answer is 38^. 3 done, 2 left today. You're making progress.
