Answer: To find the distance between bends on a 45 degree offset with a length of 40 inches and a rise of 20 inches, you can use the following formula:
Distance between bends = Length * cos(45) - Rise * sin(45)
Plugging in the given values, we get:
Distance between bends = 40 * cos(45) - 20 * sin(45) Distance between bends = 28.28 - 14.14 Distance between bends = 14.14 inches
This means that you need to measure 14.14 inches from the center of each bend to make a 45 degree offset with the given dimensions.
