>>219033Okay, for giggles, I'ma find the value of h for you.
Now, AB and EC are parallel (because it's a para-fucking-lelogram), so the "Z" rule tells us that ECA and CAB are the same.
Now, trigonometry* tells us that there is a value called the "sine" which is the ratio of the length of the hypotenuse to the length of the opposite side.
For CAB, the hypotenuse is CA and the opposite is CB. CA is 10"; CB is 5.6", so sin(CAB) is 0.56.
Now we look at ECD. D and A are collinear (on the same line), so ECD and ECA are the same angle. So they have the same sine.
The hypotenuse of ECD is EC, which is 9.8". So the opposite of ECD, which is h, must be 0.56*9.8=5.488"
* you can also do this with pythagoras.
