130°
To solve, draw a line through A parallel to BC and ED.
130°
Now we can label our two new angles x and y.
xy
130°
We know that y = 90 because drawing our new line created a rectangle.
xy
130°

We know x + 130 = 180 because Same Side Interior Angles are supplementary.
180°
x + 130 = 180-130 = -130
x + 130 = 50
