130°

130°

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°

xy

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

180°

x + 130 = 180-130 = -130

x + 130 = 50
