How do I calculate the static coefficient of friction using the equation tanè = µ when I only have the mass and angle?

that was suppose to be a tan theta thing but it came out as a funky e. just to clear that up so u not confuzzled

You just said how

$$\mu = tan(\theta)$$

$$\mu$$ is the coefficient of friction. $$\theta$$ is the MAXIMUM angle an object can be on a slope without slipping.

I could prove it for you but I really do not want to do that right now.
