Question 60973
I think the figure is a rectangle.
Length = 19.2 cm
width = 12.4 cm
With the diagonal, the figure becomes a right triangle with the length as its base and the width as its height.
 Let the angle between the diagonal and the shorter side be x
Then tanx = 19.2/12.4
          = 1.55

==> x = tan^(-1) (1.55)
      = 57 degrees.(approx)

The angle between the diagonal and the shorter side = 57 degrees.


Good Luck!!!
