\triangle A B C

is such that

\sin (2 A+B)=\frac{1}{2}

.
If

A, B

and

C

are in AP, then the values of

A, B

and

C

are

View answer and explanation

Correct option: A

\frac{\pi}{4}, \frac{\pi}{3}, \frac{5 \pi}{12}

Option A (

\frac{\pi}{4}, \frac{\pi}{3}, \frac{5 \pi}{12}

) is correct because by using the given condition and the properties of an arithmetic progression, we can find the values of A, B, and C.
