If m FDG = 50°, what is m FEG?<br><br> 75°<br> 50°<br> 100°<br> 25°<br><br> Thank you!
denpristay [2]
The measure of the angle FEG is probably the same as the measure of the angle FDG. There is nothing saying that EF is parallel to DG, but if so, the measure of the angle FEG is also 50º.
When the diagonals of a trapezium with two parallel bases inside of a circle are drawn, they make the same angle measure with those bases.
