Use the Law of Sines:
sin B sin 81 sin 44
---------- = ----------- = --------------
side AC 68 side AB
Then (side AB)(sin 81) = 68(sin 44), or
68 sin 44
side AB = ----------------------- = 47.83 units long
sin 81
Elimination Method:
5x - 4y = 6
-5x + 4y = -10
5x - 4y = 6
+ -5x + 4y = -10
————————-
0 = -4
This statement is false, so there is no solution to the system of equations.
