Construction:- Extend AB to D such … Web9 Mar 2024 · 1 Answer Sorted by: 3 Since the longest side must be opposite the largest angle in the triangle, the side which is 28 units is opposite the angle of degree measure of 120. Let us name the remaining sides a and b. Using the cosine rule we get: 28 2 = a 2 + b 2 − 2 a b cos ( 120) 784 = a 2 + b 2 − 2 a b ( − 1 2) 784 = a 2 + b 2 + a b Since a b = 240
