Angles Around a Point
Angles around a point will always add up to 360 degrees
the angles above all add to 360°
53° + 80° + 140° + 87° = 360°
Because of this we can sometimes find an unknown angle.
Example: What is angle "c"?
To find angle c we take the sum of the known angles and subtract that from 360°
Sum of known angles= 110° + 75° + 50° + 63°
= 298°
Angle c= 360° − 298°
= 62°
