Dana je kružnica $\sigma$ radijusa $1$ sa središtem u $O$ i točka $X$ na kružnici $\sigma.$ Točka $Y$ je na kružnici $\sigma$ takva da je $|XY|=r,$ i točka $Z \neq X$ je na kružnici $\sigma$ takva da je $|YZ|=r.$ Odredi kut $\angle XOZ.$ Odgovor treba napisati u stupnjevima, i treba napisati samo broj (dakle ako je odgovor $123^\circ,$ treba upisati samo 123).
