Draw  a  perpendicular line  from the top left vertex of the parallelogram to the base.

 

So...we have a right triangle  with a leg  of 5.6 in and a hypotenuse of 10 in

 

The sine of the angle at the  bottom left  vertex  =   5.6 / 10

 

And since we have a parallelogram, the angle at the top right vertex  is the same, so its sine is the same

 

So...using the Law  of Sines we have

 

9.8/ sin (90)  =    h / (5.6 / 10 )

 

9.8  =  10h / 5.6   rearrange as

 

9.8 * 5.6  / 10   =   h   =  5.488 in

 

 

cool cool cool
