In the diagram below, points A, E, and F lie on the same line. If ABCDE is a regular pentagon, and ∠ EFD = 90°, then how many degrees are in the measure of ∠FDE? (Please help me with the answer, I'm really stuck. ;-;" )

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
