જો $\sin (\alpha - \beta ) = \frac{1}{2}$ અને $\cos (\alpha + \beta ) = \frac{1}{2}$ હોય,જ્યાં $\alpha$ અને $\beta$ ધન લઘુકોણ છે,તો

  • A
    $\alpha = 45^\circ, \beta = 15^\circ$
  • B
    $\alpha = 15^\circ, \beta = 45^\circ$
  • C
    $\alpha = 60^\circ, \beta = 15^\circ$
  • D
    આમાંથી કોઈ નહીં
