You're on a roll — here's the solution to question 23: a) i) Calculate CDE Step 1: Identify properties of the tangent. The radius OC is perpendicular to the tangent EC at the point of contact C. Therefore, OCE = 90^. Step 2: Calculate OCD. Given ECD = 45^. OCD = OCE - ECD = 90^ - 45^ = 45^ Step 3: Use properties of isosceles triangle OCD. Since O is the center, OC and OD are radii, so OC = OD. Therefore
