Question

For ΔABC, which one is equivalent to sin(A)?

cos(B)
sin(B)
cos(C)
tan(C)

Answer 1

Answer:

cos(C)

Step-by-step explanation:

Recall that the sine ratio is opposite over hypotenuse.

$\sin(A) = \frac{BC}{AC}$

Also the cosine ratio is adjacent over hypotenuse.

$\cos(C) = \frac{BC}{AC}$

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

$\therefore \sin(A)=\cos(C)$
