Here are the solutions to the questions based on Fig. 12.31 and the Alternate Segment Theorem, which states that the angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment. a) Name two angles equal to AYZ. Step 1: Identify the angle AYZ. This is the angle between the tangent XYZ and the chord AY. Step 2: Apply the Alternate Segment Theorem. The angles in the alternate segment subtended by chord AY are ABY and ACY. AYZ = ABY = ACY The two angles are ABY and ACY. b) Name two angles equal to CYX. Step 1: Identify the angle CYX. This is the angle between the tangent XYZ and the chord CY. Step 2: Apply the Alternate Segment Theorem. The angles in the alternate segment subtended by chord CY are CAY and CBY. CYX = CAY = CBY The two angles are CAY and CBY. c) Name an angle equal to BYZ. Step 1: Identify the angle BYZ. This is the angle between the tangent XYZ and the chord BY. Step 2: Apply the Alternate Segment Theorem. The angle in the alternate segment subtended by chord BY is BAY. BYZ = BAY The angle is BAY. d) Name an angle equal to BYX. Step 1: Identify the angle BYX. This is the angle between the tangent XYZ and the chord BY. Step 2: Apply the Alternate Segment Theorem. The angle in the alternate segment subtended by chord BY is BCY. BYX = BCY The angle is BCY. e) If AYZ = 58^ what is ACY? Step 1: From part a), we know that AYZ = ACY. Step 2: Substitute the given value. ACY = 58^ The angle is 58^. f) If BCY = 112^ what is BYZ? Step 1: From part d), we know that BYX = BCY. BYX = 112^ Step 2: Angles on a straight line sum to 180^. BYX and BYZ are adjacent angles on the straight line XYZ. BYX + BYZ = 180^ Step 3: Substitute the value of BYX and solve for BYZ. 112^ + BYZ = 180^ BYZ = 180^ - 112^ BYZ = 68^ The angle is 68^. g) If BCY = 125^ what is BYX? Step 1: From part d), we know that BYX = BCY. Step 2: Substitute the given value. BYX = 125^ The angle is 125^. h) If BYZ = 100^ what is BAY? Step 1: From part c), we know that BYZ = BAY. Step 2: Substitute the given value. BAY = 100^ The angle is 100^. Send me the next one 📸
