Find the slope of a line whose inclination is 15 0 Share with your friends Share 2 Pooja answered this Let θ be the inclination of the required lineNow, slope, m = tan θi. θ = 15° Therefore m = tan 15° m = tan 45° - 30° = tan 45° - tan 30°1 + tan 45° tan 30° = 1 - 131 + 13 = 3 - 13 + 1 = 3 - 13 + 1 × 3 - 13 - 1 = 3 - 1232 - 12 = 3 + 1 - 233 - 1 = 4 - 232 = 2 - 3 1 View Full Answer
