<span>Gigaelectron-volts is a unit of measurement of energy, the abbreviation of gigaelectron-volts is Gev . </span>Thank you for posting your question here. Below is the solution:
0.5109989 MeV=mass of electron in (million electron volts)
0.5109989/1000=.0005109989 GeV (Giga=billion electron volts)
Since this is an obtuse triangle, Point O is not equidistant from A, B, and C. Point O is not on the perpendicular bisectors, so the third statement is true. Point O is equidistant from AB, BC, and CA because these lines are pressed against the circpe in a mannered way.
