1. The problem statement, all variables and given/known data
$\overrightarrow{a} = (58m/s^2, 40°$ below positive $x$ - axis)
Find the $x$- and $y$-components of the vector.
Express your answers using two significant figures. Enter your answers numerically separated by a comma ($a_x,a_y$).
2. Relevant equations
None I can think of.

3. The attempt at a solution
I've already done this all out on paper, it seems like simple enough trig, and should be:
$a_x = -58sin(40) = 58sin(320) = -37$ (correct to two significant figures)
$a_y = 58cos(40) = 58cos(320) = 44$ (correct to two significant figures)
Therefore, the components as a comma separated list should be "$-37,44$".

Yet this is not the answer. What am I doing wrong?

Edit: I realized after drawing it out that I switched the signs for $x$ and $y$. I'm a fool, please disregard this thread.
