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
The distance between 45 degrees and 45 degrees 30 minutes north is half a degree or 30 nautical miles.
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 northwest
No, elbow 135 degree and elbow 45 degree are different from each other.
The symbol for degrees is °, for minutes is ', and for seconds is ''. So, a measurement of 45 degrees 30 minutes 20 seconds would be written as 45° 30' 20".

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.
You find the center of a screwed 45 degree elbow by bisecting the angle.
30-45 degrees north and south of the equator
