I have a problem that I need to. I need help explaining this problem.EXPLAIN

Line AB and Line CD intersect at E, and the ratio of Angle AED is 2:3.

Write an argument to show that it is impossible for Angle DEB to be 80.

Imagine two rays that cross each other. The intersection point in the middle is E. The point in the upper left corner is A, the point in the upper right corner is D, the point in the lower left corner is C and the point in the lower right corner is B.
