Answer: Line AC = 16
Step-by-step explanation: We have two angles and one side given. The side given is facing one of the angles so we apply the Sine Rule;
a/SinA = b/SinB
We can now substitute values as follows;
AC/Sin 77 = 14/Sin 58
We cross multiply and we have
AC = (14 x Sin 77)/Sin 58
AC = (14 x 0.9744)/0.8481
AC = 13.6416/0.8481
AC = 16.08
Approximately, Line AC = 16.
