Question

In DABC, what could the 7 shown in the ratio sin A = 7/9 represent?
A) the length of the adjacent side of angle B
B) the length of the opposite side of angle A
C) the length of the hypotenuse of a right triangle
D) the length of the adjacent side of angle A

I did this as an acute angle with A at the top, i got A for my answer

Answer 1

If triangle ABC is right-triangle right angled at B or C, then
by the definition of sin(A), it is the opposite side length divided by the hypotenuse.
