Maths revision video and notes on the topic of the cosine rule, trigonometry, finding missing angles and lengths of non right angled triangles. The measures of the angles of the triangle are 27.81, 32.19, and 120 degrees. example #2: solve a triangle abc if a = 9, b = 12, and c = 10. there are no missing sides. we just need to find the missing angles. since the angle opposite the longest side is angle b, use b 2 = a 2 c 2 2ac cos(b) to find cos(b). b 2 = a 2 c 2 2ac cos(b).
