**Title: Understanding the Resultant Force Using the Parallelogram and Triangle Rules**

**Introduction:**

In this lesson, we will explore how to compute the magnitude of a resultant force acting on an anchor using the Parallelogram Law and Triangle Rule. We will also determine the angle that the resultant force makes with the positive x-axis in the counterclockwise direction.

**Problem Statement:**

Given a diagram, use the Parallelogram Law and Triangle Rule to find:

1. The magnitude of the resultant force.
2. The angle the resultant force makes with the positive x-axis.

**Diagram Explanation:**

The diagram shows:

- An anchor point with two forces acting upon it.
- A 6 kN force acting at an angle of 60° from the anchor.
- A 2 kN force acting at an angle of 45° from the anchor.
- Forces are represented by arrows originating from the anchor point, showing both direction and magnitude.

**Approach:**

- *Parallelogram Law*: Forces are represented as adjacent sides of a parallelogram. The diagonal represents the resultant force.
  
- *Triangle Rule*: Alternatively, these forces can form a triangle, allowing the use of trigonometric identities to compute the resultant.

**Conclusion:**

Through this analysis, you will gain the ability to determine both the magnitude of the resultant force and its direction relative to the x-axis. This practical knowledge is valuable in various engineering and physics applications where force vectors are involved.
