Question

In the diagram, line AB is parallel to DE. Also, line DE is drawn such that the length of line DE is half the length of line AB. If sin A=0.5, then what is sin E?

Answer 1

By alternate interior angle theorem. Angle A is congruent with Angle E.

This makes ΔAFB similar to ΔEFD.

IF sin A = 0.5, then sin E is also equal to 0.5.
