Answer:
A
Step-by-step explanation:
Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is
=
Note that AD = 33 - 22 = 11
Substitute values into the ratio
=
=
( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
To find y use similar triangles
Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal
=
, substitute values
=
=
( cross- multiply )
3y = 36 ( divide both sides by 3 )
y = 12
Thus y = 12, x = 8 → A

Well, this is a broad question but I would say pie. Pie is used very early on in secondary school and therefore a lot of people already know about it and how to use it. But for example if your a banker E would be more important as banks use e to calculate interest.
Hope this helps, have a great day.
