We know that AB = BC = AC.
Futhermore one segment cut one side in an right angle and has length of 2.
So it is a right and we can find the measure.
The opposite side of the 90 degrees must be 2x.
Where the side 2 is equivalent of the side of xSquroot3.
Since we know the length we can write as follows = 2 = xSquroot3
2/(Squroot3) = 1,15
So x = 1,15 we know that the hypothenuse equals 2X so the length must be 2 * 1,15 which is 2,3.

QA : 2,3
QB : 2Squroot3 = 3,46

B is greater
