The software rendering this question really butchered it... I think it's saying the displacement vector for the particle is
Differentiate twice with respect to time to get the velocity and acceleration vectors, respectively:
Then at , the acceleration of the particle is
which most closely resembles the first choice.

Answer:
C. 15.04°
Step-by-step explanation:
The best approach to this question is to use the Law of Sine:
We are given ∠48°, 63 on the longest side and 22 on the adjacent side (opposite of ∠B). This means we just have to set up our equation (remember to set calc to deg!!):
We solve by cross multiplying:
63sin(B) = 22sin(48°)
sin(B) =
B = sin^-1 ()
Plug the B equation into the calculator and your final answer should be 15.041°, which rounds to 15.04°.
