That's correct so C is the correct answer.
To subtract vectors, you simply have to subtract correspondent coordinates.
So, if you have

the subtraction is simply

So, in your case, we have

Answer:
B. One
Step-by-step explanation:
Since the two angles are already given, the value of the third angle is already fixed. The third angle can be found by the sum of both angles subtracted from 180. Since 2 angles and lengths are already given, there can only be 1 triangle.
Hope this helps!
If not, I am sorry.
