Re: Angle in a Parallelogram

b = 52
How ever far 52 is below 90, then "a" is above 90.
Because if you put a "L"-square carpenters tool
at "a", it makes a right triangle, and the 2 small
angles of a right triangle add up to 90, like a
30-60-90 triangle or a 45-45-90 triangle.
How far is 52 below 90?
Pretend you start at 90 and end up at 52.
|destination - origination|
|52 - 90|  (use absolute value to get rid of the word "below")
90 - 52
38 degrees
a = 38
B52's is a band and a plane.
A38 is a major road in England?
