Text Solution

AI Generated Solution

To solve triangle \( \Delta ABC \) with sides \( a = 3 \), \( b = 5 \), and \( c = 7 \), we will find the angles \( A \), \( B \), and \( C \) using the Law of Cosines and the Law of Sines. ### Step 1: Use the Law of Cosines to find angle \( C \) The Law of Cosines states: \[ c^2 = a^2 + b^2 - 2ab \cos C \] ...
