i have to do a lab to find the coefficient of friction. In this lab, we must slide a block down an inclined plane. we have to find the following forces. Fp = Force of parallel, Fn = Force of Normal, and Ff = Force of Friction. Also I have to find the coefficient of friction (μ). I have no idea how to find it but so far i have the angle of the slope (27°) and the Fw (force of weight) which is 1.1N. Youre suppose to use trignometry to find these values. Also Fp equals Ff in magnitude in this trial and you can calculate the coefficient of friction after obtaining all this other info. Ff is equal in magnitude and opposite in direction to Fp. I've provided an rough image of how everything looks like.

The normal force is
Fn=Fw*cos(27)
The force of gravity parallel to the slope is
Fp=FW*sin(27)
Just when the block slides
FW*sin(27)=Fw*cos(27)*μ
note that μ=tan(27)
