WebThe cosine formulae given above can be rearranged into the following forms: Key Point a 2= b2 +c −2bccosA b 2= c +a −2cacosB c2 = a 2+b − 2abcosC If we consider the formula c2 = a2 +b2 − 2abcosC, and refer to Figure 4 we note that we can use it to find side c when we are given two sides (a and b) and the includedangle C. WebStep 2: Find the nature of triangle: b 2 + c 2 = k 2 4 + k 2 12 = 4 k 2 12 = k 2 3 = a 2. So A = 90 ° S i n B = b a = 3 2. So, B = 60 ° C = 30 ° So, the triangle is right angled with A = 90 °, B = 60 … pt ptt activated
