Question

Find sin(B).

1. a/b

2. a/c

3. b/a

4. b/c


5. c/a


6. c/b

Answer 1

4. b/c

Explanation:

In a right-angled triangle with sides of lengths a, b, and c, where c is the hypotenuse (the side opposite the right angle), the sine of the angle opposite side b (angle B) is given by:

Sin theta : Opposite/hypotenuse

sin(B) = b/c

Therefore, the answer is 4. b/c
