Concurrency Of Three Lines And Family Of Straight Lines

Concurrent Lines or Intersecting Lines

Angles made by a transversal with two lines

If a line makes angles of measure 45^(@) and 60^(@) with the positive direction of the Y and Z axex respectively, then the angle made by the line with the positive directions of the X-axis is
