WebCosine rule is also called law of cosines or Cosine Formula. Suppose, a, b and c are lengths of the side of a triangle ABC, then; a2 = b2 + c2 – 2bc cos ∠x. b2 = a2 + c2 – 2ac cos ∠y. c2 = a2 + b2 – 2ab cos ∠z. where ∠x, ∠y … WebExpert Answer. Question 5 - Trigonometry 5.a) A triangle has sides of length 5,6 , and 7 metres. Use the Cosine Rule to calculate the smallest angle in the triangle correct to one decimal place. 5.b) The length of the base of the triangle below (i.e. the two lengths b and d added fogether) is 19 cm. Given the other side lengths and angle sizes ...
