Example 1: 120° Example 2: 30° Example 3: 225°

Example 1: 120 x π/180 Example 2: 30 x π/180 Example 3: 225 x π/180

Example 1: 120 x π/180 = 120π/180 Example 2: 30 x π/180 = 30π/180 Example 3: 225 x π/180 = 225π/180

Example 1: 120 x π/180 = 120π/180 ÷ 60/60 = 2/3π radians Example 2: 30 x π/180 = 30π/180 ÷ 30/30 = π/6 radians Example 3: 225 x π/180 = 225π/180 ÷ 45/45 = 5/4π radians

Example 1: 120° = 2/3π radians Example 2: 30° = 1/6π radians Example 3: 225° = 5/4π radians
