Tan240°×(sin45°+cos30°)​

Penjelasan dengan langkah-langkah:

tan 240° × (sin 45° + cos 30°)​

tan 240° = tan (180°+60°) = tan 60° = sqrt{3} (kwadran 3, tan bernilai positif)

sin 45° = frac{sqrt{2} }{2}

cos 30° = frac{sqrt{3} }{2}

tan 240° × (sin 45° + cos 30°)​

sqrt{3} (frac{sqrt{2} }{2} +frac{sqrt{3} }{2})

sqrt{3} (frac{sqrt{2}+sqrt{3}}{2})

frac{sqrt{6}+3}{2}
