Force Problem, Fuzzy Dice hanging from a rearview mirror

[cmsoccer21]

Homework Statement

Heres the problem, I've done these kind of problems before but it has been about a year for me since I've done one and I can't seem to remember how to anymore:
A pair of “fuzzy dice” hangs from a string attached to the rear view mirror of a race car moving with constant acceleration. Find the acceleration if the string makes a 70° angle with the vertical.

Homework Equations

F=MA

The Attempt at a Solution

I am not sure where to start other than I drew a triangle with a 70 degree angle. If someone could just please give me a place to start off from, I would really appreciate it. Thanks!

A free-body diagram would a good place to start. Identify all the forces acting on the dice, what can you say about these forces?
