Final answer:
To determine the angle θ between the two cables attached to the pipe, use the dot product formula in trigonometry.
Step-by-step explanation:
To determine the angle θ between the two cables attached to the pipe, we need to use trigonometry. Let's assume the cables are represented by vectors A and B. The dot product of two vectors is given by the product of their magnitudes and the cosine of the angle between them: A·B = |A||B|cosθ. We can rearrange this equation to solve for θ: θ = arccos((A·B)/(|A||B|)). By substituting the values of A and B, we can calculate the angle θ.
