Basic Angle Chasing

         

Line segments AB\overline{AB} and CD\overline{CD} intersect at point O.O. If AOC+BOD=78,\color{#69047E}{\angle AOC}+\color{#D61F06}{\angle BOD}=78 ^\circ, what is the measure (in degrees) of AOD?\color{#20A900}{\angle AOD}?

Three line segments AB,\overline{AB}, CD\overline{CD} and EO\overline{EO} intersect at point O.O. If the blue angle BOC=139\color{#3D99F6}{\angle BOC = 139^\circ} , what is the measure of the yellow angle?

Given that AB\overline{AB} is a straight line, what is xx?

In the above diagram, the purple angle at C\color{#69047E}{C} equals 147 \color{#69047E}{ 147}^\circ and the blue angle at B\color{#3D99F6}{B} equals 123 \color{#3D99F6} {123} ^ \circ . What is the measure of the green angle at A\color{#20A900}{A}?

Note: The diagram is not drawn to scale.

In the above diagram, line segments AB\overline{AB} and CD\overline{CD} intersect at point E.E. If AED=52,\angle AED={52}^\circ, what is the measure of CEB\angle CEB in degrees?
