If the incline is completely flat and the coefficient of friction is for static friction, then you can find the largest angle for which the mass wont slide by noting that the maximum force along the slide is usually modeled simply as the normal force times the coefficient, and you can equate that with the force from gravity down the incline, that is,

[tex] \mu F_n = \mu mg \cos(\alpha) = F_g = mg \sin(\alpha) \ \Rightarrow \ \tan(\alpha) = \mu [/tex]

where [itex]\alpha[/itex] is the angle and [itex]\mu[/itex] the coefficient of static friction.

Hi Sinnaro! Welcome to PF!

I'm not sure whether you're talking about sliding (which as

If it's toppling, then all that matters is whether a vertical line through the centre of mass goes outside the base.

Picture of what I'm talking about. Assume that the mass looks similar to my drawing (tall vertical height with wide base):
