LOL er guys, that shape is a trapezium, the diagram is dodgy

Realistically, an "earth embankment" shouldn't be a trapezium.. this is clearly an irregular shape

Once you realise it's a trapezium it's fairly straightforward. Just drop perpendiculars to find the height and you can use trig to find the difference between top and bottom.

Wow, so it was the diagram that put everyone off...

Also, by definition, isn't a trapezium defined by a shape with one pair of parallel sides? o.o.

Look at the angles, cointerior angles are supplementary. Those ARE parallel lines, just drawn to not look like they are.
