You need the Law of Cosines here, since you only have 1 angle measure.  If you had 2 you could use the Law of Sines, but nevertheless, we'll get there.  The Law of Cosines for our particular set of info looks like this: x^2=65^2+41^2-2(65)(41)cos(35).  Simplifying a bit we get x^2=4225+1681-4366.080396 and x^2=1539.9196.  Taking the square root of that and considering the principle root only, x = 39.2, second choice down.

The graph shows two lines, A and B.
EastWind [94]

Answer:


Part A: one solution:

Part B: x = 3, y = 4.


Explanation:


1) Part A: how many solutions does the pair of equations for lines A and B have?


The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.


In this case, there are two straight lines, which intersect in one and only one point.


Hence, the system has one solution.


2) Part B: what is the solution to the equations of lines A and B?


The solution is the pair of coordinates of the intersection point. It is (3, 4).


Therefore, the solution is x = 3, y = 4.
