Your 71,1482 doesn't make sense. But regardless,
let x = the other car's cost.
You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.
You can do $38,295 + c = $71,1482.
Or $71,1482 - $38,295 = c.
Twelve and thirty- eight hundredths.
To get y you can move the x's to one side, so 120y=500-35x
then you can isolate the y, y= 500/120-35x/120

The answer is 46.
Since the sum of the interior angles of a triangle is always 180,
We can find out angle C by subtracting the other two angles
180-102-32=46
