I believe it is C, there is a geometric law that states that the opposite angles across a line with both going into parallel lines will be the same angle. Rather confusing but a video online would likely explain it better than anyone could here.
Answer:
Option C. 0.5
Step-by-step explanation:
In the given diagram, AB is parallel to DE, and line AE is the transverse.
So ∠DEF ≅ ∠FAB [ Alternate angles ]
and ∠EFD ≅ AFB ≅ 90° [ Vertically opposite angles ]
So, Third angle of the triangles will also be equal.
Since angles DEF and FAB are equal so their sine values will also be equal.
Therefore, sinA = sinE = 0.5
Option C). 0.5 will be the answer.
