The longest side in the given ΔABC is AB And, The angle opposite to the longest side is largest ∠C is the largest angle. in the ΔABC find the measure of ∠C Now, Using law of cosine in the given ΔABC : 16² = 9² + 12² - 2 × 9 × 12·cos C 216·cos C = 81 + 144 - 256 216·cos C = -31 cos C = -0.14352 m∠C ≈ 98°

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
