Web13 jun. 2024 · To work out the size of angles b and c, we will first find the sum of the three angles above. 100° + 120 ° + 120° = 340°. We can subtract this from 540° to get 200°. This means that angles b and c must add together to make 200°. Since they are both the same size, we will just divide 200° by 2. Angle b = 100° and angle c = 100°.
