Finding Missing Angle Worksheet Download - Free Printable

I will solve this worksheet by determining the value of the missing angle 'A' in each of the 12 problems. The key concept here is that a full circle is 360 degrees, and the angles shown are parts of that circle.

For each problem, I can see two angles marked on the diagram: one given as a specific degree measure and another labeled 'A'. These two angles together form a complete circle (360°). Therefore, to find the value of 'A', I will subtract the given angle from 360°.

Let me go through each problem one by one.

Problem 1:
- Given angle: 133°
- Missing angle A = 360° - 133° = 227°

Problem 2:
- Given angle: 155°
- Missing angle A = 360° - 155° = 205°

Problem 3:
- Given angle: 149°
- Missing angle A = 360° - 149° = 211°

Problem 4:
- Given angle: 160°
- Missing angle A = 360° - 160° = 200°

Problem 5:
- Given angle: 107°
- Missing angle A = 360° - 107° = 253°

Problem 6:
- Given angle: 161°
- Missing angle A = 360° - 161° = 199°

Problem 7:
- Given angle: 124°
- Missing angle A = 360° - 124° = 236°

Problem 8:
- Given angle: 108°
- Missing angle A = 360° - 108° = 252°

Problem 9:
- Given angle: 39°
- Missing angle A = 360° - 39° = 321°

Problem 10:
- Given angle: 115°
- Missing angle A = 360° - 115° = 245°

Problem 11:
- Given angle: 148°
- Missing angle A = 360° - 148° = 212°

Problem 12:
- Given angle: 114°
- Missing angle A = 360° - 114° = 246°

Now, I will compile these answers for the final response.

The values for the missing angle 'A' are:
1. 227°
2. 205°
3. 211°
4. 200°
5. 253°
6. 199°
7. 236°
8. 252°
9. 321°
10. 245°
11. 212°
12. 246°
