Question

What is the angle between vector v and the positive direction of the x-axis?

A) Supplementary angle
B) Complementary angle
C) Right angle
D) Obtuse angle

Answer 1

The angle between vector v and the positive direction of the x-axis can be determined using trigonometry.

Step-by-step explanation:

Angle between vector v and positive x-axis:

The angle between vector v and the positive direction of the x-axis can be determined by using trigonometry. If we have the coordinates of vector v in the x and y dimensions, we can calculate the angle using the arctan function.

Let's say vector v has components (vx, vy):

1. Calculate the arctan(vy/vx) to get the angle in radians.
2. To convert the angle to degrees, multiply the result by 180/π.

This angle will give you the direction of vector v with respect to the positive x-axis.
