It is an obtuse triangle
The complement to an angle is how much it takes to make 90 degrees. The complement to 30 degrees is 60 degrees. The complement to 45 degrees is 45 degrees.
Elbow is a fitting used to change pipe direction, 45 degrees in this case, LR is referred as "long Radius" ( normally most pipes, unless you ask for SR, short radius). Butt weld refers to welding 2 ends from two separate fittings or pipe. Both ends are beveled (30 degrees is tapered from inside pipe diameter to outside pipe diameter on pipe/fitting connections)
You find the center of a screwed 45 degree elbow by bisecting the angle.
They are: 90 degrees, 45 degrees and 45 degrees
30
At each vertex, the mitre needs to turn the trim through 45 degrees. Therefore, at each mitre the outer edge of the trim must be 22.5 degrees (a quarter of a right angle) further out.
The distance between 45 degrees and 45 degrees 30 minutes north is half a degree or 30 nautical miles.
the northwest
No, elbow 135 degree and elbow 45 degree are different from each other.
It is an obtuse triangle
The main difference between a 5d and a 10d 45-degree elbow is the radius of the curved portion. A 5d elbow has a radius of five times the nominal diameter, while a 10d elbow has a radius of ten times the nominal diameter. This means that the 10d elbow will have a larger curve, requiring more space for installation compared to the 5d elbow.
A location at 30 degrees south and 45 degrees east is in the southern and eastern hemispheres, and it is east of the prime meridian.

A location that is 30 degrees south and 45 degrees east is not on the Prime Meridian but is on the equator. The Prime Meridian is at 0 degrees longitude and runs through Greenwich, England.
