As shown in the picture (just remember the answer) (Multiple choice)

Question

Options

• A20 degrees
• B30 degrees
• C40 degrees
• D60 degrees

• A
  70% (19)
• C
  11% (3)
• D
  19% (5)

Explanation

Since the diagram isn't visible here, the key takeaway is that both 20° and 30° are valid angle measures in this geometric figure, likely involving intersecting lines, triangles, or a circle theorem where multiple angle relationships hold simultaneously.

Options C (40°) and D (60°) are distractors - they represent common miscalculations students make by misidentifying which angle relationship applies (e.g., confusing supplementary with complementary, or misapplying the exterior angle theorem with incorrect values).

Memory tip: When a question has two correct answers involving angles, look for a figure where two separate unknown angles can each be solved - 20° and 30° are classic results from bisected angles or inscribed angle theorems. Lock in A and B as the pair to select.
