Ex 3.1, 2 Find the degree measures corresponding to the following radian measures ("use " π" = " 22/7) (iv) 7𝜋/6 We know that Radian measure = 𝝅/𝟏𝟖𝟎 × Degree measure 7𝜋/6 = 𝜋/180 × Degree measure 7𝜋/6 × 180/𝜋 = Degree measure (𝟕 × 𝝅 ×𝟏𝟖𝟎)/(𝟔 × 𝝅) = Degree measure 210 = Degree measure Degree measure = 210°
