ECZ 2017 · GCE Paper 1 — Circle Theorems
In the same diagram (BD a diameter, AĈB = 42°, CÂD = 33°), find AĈD.
- A. 48°
- B. 33°
- C. 42°
- D. 57°
Verified working — step 1
Work in ARCS, letting the diameter do the heavy lifting: BD splits the circle into two 180° halves.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
