Answer:

Please help using law of cosines!
Tamiku [17]

Answer:

∠ A ≈ 48°

Step-by-step explanation:

Using the Cosine rule to find an angle

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

with a = 10, b = 13 and c = 11

cosA = \frac{13^2+11^2-10^2}{2(13)(11)}

         = \frac{169+121-100}{286}

         = \frac{190}{286} , thus

A = cos^{-1} ( \frac{190}{286} ) ≈ 48° ( to the nearest degree )
