This problem can be tackled using the equivalence principle. This basically means that the accelerating car can be thought of from the perspective of the hanging object, as a horizontal gravitational field, with an acceleration equal to that of the car.
Therefore we effectively have two forces acting on the object. One downwards of mg, the other horizontally of ma, where a is the acceleration of the car.
The angle of the resultant force is given by tanθ=mamg=ag
Therefore a=gtanθ
