there's a simple equation to get the [H+]. then u can get pH.
[H+] = the square root of Ka x Ma (Ma is the molarity of the acid, Ka is the Ka of the acid.) the Ka of acetic acid is 1.8x10^ -5.
[H+] = sqrt (0.1x1.8x10^ -5)
[H+]=0.00134
to get pH take the negative log of that.
- log 0.00134 = 2.87

the explanations are based on the RICE method, which is used for weak acids and weak bases

[H+] = root (Ka x 0.1).
Now you have to go and look up Ka!
