In the diagram below, de is parallel to xy . what is the value of x?

DE is parallel to XY, so the corresponding angles are congruent. 

Therefore, x = 110 degrees

Corresponding angles are pairs of angles that are on the same corresponding side of the parallel line. In this case, both are above their respective horizontal line. Also, corresponding angles are on the same side of the transversal line (in this case, the left side)

The ratio would be 3:1

2 dozen= 24 so the ratio would be 24:8 but both numbers are divisible by 8
