Question 1044011: What are the dimensions of a rectangle with diagonals of 26 cm and diagonals that intersect at 44 degrees? Answer by ikleyn(52781) (Show Source):
One side is 13*cos(22°).
The other side is 13*sin(68°).
Here 13 is half of the diagonal (because diagonals of a rectangle/parallelogam bisect each other),
22° = ,
68° = 90° - 22°.
