PLEASE HELP LAW OF COSINES
chubhunter [2.5K]
The Law of Cosine states
cosC=(a^2+b^2-c^2)/2ab

so plugging in the numbers gives us

cosJ=(13^2+19^2-11^2)/2(13*19) = 409/494

We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos(409/494)=34.11
rounding your answer will give you 34°
