Morning Koki — let's get this done. Here are the solutions for the geometry problems: d) Step 1: Identify the given information. We are given that line AT is tangent to the circle at B. Angle ABT = 80°. Chord BC = Chord CD (indicated by the double dashes). We need to find the value of x, which is BDC. Step 2: Apply the Alternate Segment Theorem. The angle between the tangent AT and the chord BD is ABT. This angle is equal to the angle subtended by the chord BD in the alternate segment, which is BCD. So, BCD = ABT = 80^.
