  (d)  ΔABC ~ ΔFED

Step-by-step explanation:

All of the answer choices start with ΔABC, so the first-named vertex is the one with no angle marking. In the smaller triangle, that is vertex F.

Only one answer choice matches vertex A with vertex F:

  ΔABC ~ ΔFED

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
