Solution 1

The direction cosines of a line are the cosines of the angles that the line makes with the positive directions of the coordinates axes. They are usually denoted by l, m, n.

Given the equations l + m + n = 0 and l^2 = m^2 + n^2, we can find the angle between the lines using the formula for the dot Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
