if one of the angles measures 51.3, then the angle opp to the angle is also 51.3
the remaining angles will be equal to each other.
let them equal to x
now, the sum of the angles in a quad is 360
therefore, 51.3 +51.3 + x + x = 360
102.6 + 2x = 360
2x = 257.4
x = 128.7
therefore the measure of all angles are 51.3, 51.3, 128.7 and 128.7
the remaining angles will be equal to each other.
