For ΔABC, which one is equivalent to sin(A)? cos(B) sin(B) cos(C) tan(C)

krek1111 [17]

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.

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

The following sequence is arithmetic. 18, 11, 4, -3, -10, -17….

Romashka-Z-Leto [24]

Hello,

It is true that the sequence is arithmetic. Its common difference, of subtracting 7 each time, is always going to subtract 7 from each number.

Hope this helps!
