Ex 10.3, 6 Find the distance between parallel lines 15x + 8y โ 34 = 0 and 15x + 8y + 31 = 0 We know that , distance between two parallel lines Ax + By + C1 = 0 & Ax + By + C2 = 0 is d = |๐ถ_1โ ๐ถ_2 |/โ(๐ด^2 + ๐ต^2 ) Equation of first line is 15x + 8y โ 34 = 0 Above equation is of the form Ax + By + C1 = 0 where A = 15, B = 8 & C1 = โ 34 Equation of second line is 15x + 8y + 31 = 0 Above equation is of the form Ax + By + C2 = 0 where A = 15 , B = 8 , C2 = 31 Distance between parallel lines 15x + 8y โ 34 = 0 and 15x + 8y + 31 = 0 is d = |๐ถ_1โ ๐ถ_2 |/โ(๐ด^2 + ๐ต^2 ) Putting values d = |โ34 โ 31|/โ(ใ(15)ใ^2 + (8)^2 ) d = |โ34 โ 31|/โ(225 + 64) d = |โ65|/โ289 d = 65/โ(17 ร 17) d = 65/17 Thus, the required distance is ๐๐/๐๐ units
