A) 2
B) 1
C) 0.5
D) 0.25
E) 0.1

Answer 1

C.

0.5

Explanation:

Answer 2

C) 0.5

Explanation:

Since DE is parallel to AB, angle FDE = ABF and DEF = angle FAB

In fact, both triangles (ABF and DEF) are similar to each other because their interior angles are identical.

So, if sin(A) = 0.5, sin(E) = 0.5 too.
