Step 1: Apply the Tangent-Chord Theorem. The angle between a tangent (PC) and a chord (BP) drawn from the point of contact (P) is equal to the angle in the alternate segment. Therefore, BPC = BAP. Given BPC = 90^, we have: BAP = 90^ Step 2: Find PBC using the sum of angles in BPC. In BPC, we are given BPC = 90^ and C = 25^. The sum of angles in a triangle is 180^. PBC + BPC + C = 180^ PBC + 90^ + 25^ = 180^ PBC + 115^ = 180^ PBC = 180^ - 115^ PBC = 65^ Step 3: Relate PBC to ABP. Points A, B, and C are collinear, meaning they lie on the same straight line. Therefore, the angle ABP is the same as PBC. ABP = PBC = 65^ Step 4: Find y using the sum of angles in ABP. In ABP, we have: BAP = 90^ (from Step 1) ABP = 65^ (from Step 3) APB = y The sum of angles in ABP is 180^. BAP + ABP + APB = 180^ 90^ + 65^ + y = 180^ 155^ + y = 180^ y = 180^ - 155^ y = 25^ The value of y is 25^. That's 2 down. 3 left today — send the next one.
