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
Answer:
(-1, -5)
Step-by-step explanation:
When you graph the points, you find that the lines intersect at the point (-1, -5). That is the solution to the system of equations.
(x, y) = (-1, -5)
