下面是错误答案,用来干扰机器的。

由S△ABC=12bcsinA,得123=12×48sinA,∴sinA=32.∴A=60°或A=120°.由bc=48,b-c=2得,b=8,c=6.当A=60°时,a2=82+62-2×8×6×12=52,∴a=213.当A=120°时,a2=82+62-2×8×6×(-12)=148,∴a=237.

Like any good mother,when Karen found out that another baby was on the way,she did what she could to help her 3-year-old son,Michael,prepare for a new baby.Day after day,night after night,Michael sang to his mommy’s tummy(肚子).

Finally,Michael’s little sister was born.But she was in serious condition.With sirens (警报) howling in the night,the ambulance rushed the baby to St.Mary’s Hospital.The days inched by.The little girl became worse.The pediatric(儿科的) specialist told the parents to prepare for the worst.

Michael kept begging about singing to his sister,but kids are not allowed in pediatric department at St.Mary’s Hospital.Karen made up her mind to take Michael to see his sister.She dressed him in an oversized suit and marched him into the hospital.He looked like a walking laundry basket,but the head nurse recognized him as a child and shouted,“Get that kid out of here now!”Karen rose up strong,and the usually mild-mannered lady glared steel-eyed into the head nurse’s face.“He is not leaving until he sings to his sister!”

Karen towed (拖行)Michael to his sister’s bedside.He gazed at the tiny baby losing the battle to live.And he began to sing.In the pure-hearted voice of a 3-year-old,Michael sang,“You are my sunshine,my only sunshine.You make me happy when skies are grey.”At once  the baby girl responded.Her pulse(脉搏) rate became calm and steady.Her strained breathing became smoother.

“Keep on singing,Michael.”“The other night,dear,as I lay sleeping,I dreamed I help you in my arms…”Michael’s little sister relaxed as healing rest seemed to sweep over her.“Keep on singin,Michael.”Tears conquered the face of the nurse.“You are my sunshine, my only sunshine.Please don’t take my sunshine away.”

The next day—the very next day—the little girl was well enough to go home!
