Angles around a point, step by step

Angles fanning all the way around a single point fill a full turn: together they add to 360°.

The question
x125°140° degrees

Angles around a point: x, 125°, 140°

125° + 140° + x=360°
125° + 140°=265°
360° − 265°=95°
  1. The angles around a point add up to 360°, so all three together make 360°.
  2. Add the two you are given first: 125 + 140 = 265.
  3. Then take that from 360°: 360 − 265 = 95. So x = 95°.

How it works.

  1. 01

    The angles around a point add up to 360°, so all three together make 360°.

  2. 02

    Add the two you are given first: 125 + 140 = 265.

  3. 03

    Then take that from 360°: 360 − 265 = 95. So x = 95°.
