Answer key · Angles around a point
1. 240
Angles around a point add up to 360°.
360 − 120 = 240, so the missing angle is 240°.
2. 215
Angles around a point add up to 360°.
360 − 145 = 215, so the missing angle is 215°.
3. 205
Angles around a point add up to 360°.
360 − 155 = 205, so the missing angle is 205°.
4. 275
Angles around a point add up to 360°.
360 − 85 = 275, so the missing angle is 275°.
5. 320
Angles around a point add up to 360°.
360 − 40 = 320, so the missing angle is 320°.
