Answer:

Choice C

Step-by-step explanation:

Actually you need not even compute anything for this answer. The vector is located in the first quadrant where both x and y components of the vector are positive

That is because the y component points up and x component points right

The only choice which has both components positive is choice C

However if you were to calculate we would do so as follows

Vx = x component = v cosΘ where Θ is the angle of the vector with the x-axis

Vx = 12 x cos 25 = 12 x 0.906 ≈ 10.875 ≈ 11

Vy = 12 x sin25 = 12 x 0.4226 ≈ 5.07 or 5.1

So it is choice C
