\tan \beta=\frac{12}{5}

, then the value of

\sin (\beta-\alpha)

View answer and explanation

Correct option: D

\frac{171}{221}

The correct answer is

\frac{171}{221}

because it is the result of applying the sine subtraction formula and using the given information to find the values of sine and cosine.
