Angles on a line and around a point, step by step
Angles that sit side by side share what is left of the whole.
The question
degrees
Angles around a point: 120°, 95°, x
120° + 95° + x=360°
120° + 95°=215°
360° − 215°=145°
- The angles around a point add up to 360°, so all three together make 360°.
- Add the two you are given first: 120 + 95 = 215.
- Then take that from 360°: 360 − 215 = 145. So x = 145°.
How it works.
- 01
The angles around a point add up to 360°, so all three together make 360°.
- 02
Add the two you are given first: 120 + 95 = 215.
- 03
Then take that from 360°: 360 − 215 = 145. So x = 145°.
