3" height by 1.5" Length with a 3/4" angle
What is the degree of the bend?
The angle (Theta) is 28.9550 decimal degrees, measured by the chord length of 3/4” (point on arc to point on arc), which forms an Isosceles triangle.
The formula is: Theta = arcsine (0.5 * opposite side / hypotenuse)) * 2, so:
Theta = arcsine (0.5 * 0.75” /1.5”)) * 2;
Theta = arcsine (0.375 /1.5)) * 2;
Theta = arcsine (0.25)) * 2;
Theta = 14.477512 * 2;
Theta = 28.9550º or in DMS format: 28º 57’ 18”
