In ∆ABC , if B= 60° , C = 3cm and A = 12cm . what is the area of ∆ABC?​

9514 1404 393

  15.6 cm²

Step-by-step explanation:

The area is given by the formula ...

  area = 1/2ac·sin(B) = 1/2(12 cm)(3 cm)sin(60°) ≈ 15.58846 cm²

The area of ΔABC is about 15.6 cm².

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
