If a coordinate system is set up such that the positive x axis points in a direction 75° above the horizontal, what should be the angle between the x axis and the y axis?
It is best to keeop the x and y axes perpendicular.
90 degrees
To find the angle between the x-axis and the y-axis, we can consider the given information that the positive x-axis points in a direction 75° above the horizontal.
Let's visualize the coordinate system. The positive x-axis is a line in the upward direction with an angle of 75° above the horizontal.
To find the angle between the x-axis and the y-axis, we need to consider that the y-axis should be perpendicular to the x-axis.
Since the x-axis points 75° above the horizontal, the y-axis should be perpendicular to it, which means it should be 90° away from the x-axis.
Therefore, the angle between the x-axis and the y-axis should be 90°.
