Worked Solution
Step 1: Identify the whole angle being split: 145°.\n
Step 2: Identify one of the two parts: 90° (the flag pole is perpendicular to the ground).\n
Step 3: To find the other part, subtract the known part from the whole: 145° − 90° = 55°.\n
Step 4: Check by adding back: 90° + 55° = 145° ✓.
Answer: 55°
Correct answer: 55°
