$μ = \tan\theta$ - Why? It makes sense mathematically, but if it's based on the materials...

    We were presented with a problem in physics today in which we calculated that the coefficient of static friction is equal to the tangent of an angle

    This is on a ramp using the laws of friction.

    My question here is... how? Like I get that it makes sense mathematically and all, but isn't it something to with the materials? My professor gave me a cryptic answer regarding "imperfect models" but told me to figure it out. This is me figuring it out I'll post a response if I end up making sense of it.
