This is just a calculator problem.
+/- This will turn 68 into a minus when you enter it. On some calculators it is the (-) key.
68
÷
255
=
-0.266666666 is what you should get.
F would be 1. G would be 4. E would be negative 3
Angle ABC = 130
Angle ABC = Angle ADC = 130 (Opposite angles are equal)
Angle DAB = 180 - 130 = 50 (consecutive interior angles)
I HOPE IT IS HELPFUL:D
They are both equivalent to 1, so they are equal.
