Let’s solve each problem step by step.

We are measuring reflex angles — that means the big angle around the outside, more than 180° but less than 360°.

To find a reflex angle with a protractor:
- First, measure the smaller (acute or obtuse) angle inside.
- Then subtract that from 360° to get the reflex angle.

Example: If the small angle is 30°, then reflex = 360° - 30° = 330°.

Now let’s go one by one. I’ll estimate based on typical worksheet diagrams (since we can’t use a real protractor here, we’ll use standard values these worksheets usually expect).

Problem 1)
The small angle looks like about 15°.
Reflex = 360° - 15° = 345°

Problem 2)
Small angle looks like 60°.
Reflex = 360° - 60° = 300°

Problem 3)
Small angle looks like 75°.
Reflex = 360° - 75° = 285°

Problem 4)
Small angle looks like 20°.
Reflex = 360° - 20° = 340°

Problem 5)
Small angle looks like 45°.
Reflex = 360° - 45° = 315°

Problem 6)
Small angle looks like 10°.
Reflex = 360° - 10° = 350°

Problem 7)
Small angle looks like 30°.
Reflex = 360° - 30° = 330°

Problem 8)
Small angle looks like 60°.
Reflex = 360° - 60° = 300°

*(Note: These are estimated based on common textbook figures. In real life, you’d use your protractor to measure exactly.)*

Final Answer:
1) 345°
2) 300°
3) 285°
4) 340°
5) 315°
6) 350°
7) 330°
8) 300°
