Answer:

  (b)  sin(B) = cos(90°-B)

Step-by-step explanation:

You want the relation that is true in the triangle.

Relation

No triangle is shown, so we do not know the relation between angles A and B. However, the relation between sine and cosine that is true for any angle is ...

  sin(B) = cos(90° -B) . . . . . . . matches choice B
