The Diagram Shows Triangle Abc A 81в Ab 8 2 Cm The length of the side ac of the triangle abc whose side ab is of 8.2 cm and side bc is of 13.5 cm length with angle a of 81° is 12.1 cm approx what is law of cosine? let there is triangle abc such that |ab| = a units, |ac| = b units, and |bc| = c units and the internal angle a is of θ degrees, then we have:. In triangle abc, ab=8.2 cm, c=13.5 cm and angle a= 81 degrees. to find: the length of ac. solution: according to the law of sines: using law of sines, we get. using angle sum property, we get. now, therefore, the length of ac is 12.08 cm.
The Diagram Shows A Triangle Abc The diagram below shows a sketch of the triangle abc with ab = xcm, bc 15. (x 5)cm, (b) (c) 7 cm and cos bac = x cm (x 5)cm 7 cm [3] [3] write down an equation satisfied by x. hence show that x find the exact value of the area of triangle abc. the point d lies on bc and is such that ad is perpendicular to bc. find the length of ad. [2] 3. The diagram shows triangle abc with point g inside. cb = 11 cm, cg = 5.3 cm and bg = 6.9 cm. angle cab = 42° and angle acg = 54°. calculate the value of . Triangle calculator.
