Realistically, an "earth embankment" shouldn't be a trapezium.. this is clearly an irregular shapeLOL er guys, that shape is a trapezium, the diagram is dodgy

Wow, so it was the diagram that put everyone off...View attachment 31039
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.
Also, by definition, isn't a trapezium defined by a shape with one pair of parallel sides? o.o.Wow, so it was the diagram that put everyone off...
No not even, this question is Year 10 Advanced Maths.Is This 2u?
Look at the angles, cointerior angles are supplementary. Those ARE parallel lines, just drawn to not look like they are.Also, by definition, isn't a trapezium defined by a shape with one pair of parallel sides? o.o.
