Question

Use the given triangle to fill in the blank.bCasin BB

Answer 1

We can apply trigonometric ratios, on this case we ned to use sine

`\sin (\alpha)=(O)/(H)`

Where alpha is th reference angle, O the opposite side from the reference angles and H the hypotenuse of the triangle

On our case O is b and H is c, then replacing

`\sin (B)=(b)/(c)`

then sinB is b/c, then right option is first
