Answer:

d

Step-by-step explanation:

Using the Cosine rule to find ∠ A

cosA = \frac{b^2+c^2-a^2}{2bc}

         = \frac{5.1^2+5.7^2-7.3^2}{2(5.1)(5.7)}

         = \frac{26.01+32.49-53.29}{58.14}

         = \frac{5.21}{58.14} , then

∠ A = cos^{-1} ( \frac{5.21}{58.14} ) ≈ 84.9° ( to 1 dec. place )
