I need help understanding how to determine the deviation amount in the shaded area of the pipeline single-line diagram

The last edit to this post was made by Desert Fish on 2020-8-22 at 21:03. As shown in the diagram, ↖ represents true north; how can one determine the degree of deviation in the shaded area?
The title should fully convey the question to facilitate discussion. This diagram shows two 45-degree tilts: one in the vertical direction and one in the horizontal direction
Arrived in a state of confusion, left in a state of confusion
The horizontal tee leads in the “southwest” direction, connecting to a 90-degree elbow. I’m not sure if this pipe fitting number 4 is a 90-degree elbow. See the sketch below for reference only.
The three-way branch is due southwest. As for the deviation, it is 45 degrees west of south. The shaded triangle on the left is an isosceles right triangle, with both legs having a length of 465. The shaded right triangle is also an isosceles right triangle, with both legs having the same length of 418.
With the lengths of all three sides of the shaded area known, its orientation can be determined quite easily
When looking at such diagrams, angles are generally not taken into consideration. In this case, since both values are 465 or 418, it can be concluded that the angle is 45 degrees; if the two values are not equal, then an angle cannot be used to explain it. Interpret the drawings using the most basic methods; for example, in the case of 465, draw a triangle on paper, move 465 units north and 465 units west, then connect the vertices of the triangle – the length and angle can be determined using this final side.
These two represent a swing angle of 45 degrees in the plane, with the ultimate goal of achieving a 90-degree angle
Thank you to all the teachers for their explanations; thank you

This is a great question; come in and learn* it
