What is the measure of the blue angle in degrees?

In the figure above, $$AE$$ is the diameter of the circle.
What is the measure of $$\angle ABC+\angle CDE$$ in degrees?

Three line segments $$AD, BE, CF$$ intersect at a single point in the diagram above. Find the sum of the angles $$a+b+c+d+e+f$$ in degrees.

In a parallelogram $$ABCD$$, the length of $$AB$$ is twice the length of $$AD$$. $$E$$ is the midpoint of $$AB$$. Find the measure of $$\angle DEC$$.

As shown in the diagram above, there lie 3 squares between 2 parallel lines such that each pair--(line, square) or (square, square)--just meet at a vertex. Find the measure of angle $$x$$ in degrees.
