Answer:
Angle DAB is congruent to Angle CAE by Vertical Angle Theorem
2x+6=96 by Vertical Angle Theorem.
Explanation:
Vertical Angles are angles which are across from each other but share a vertex. These angles are always congruent and can be proven by reflection. In the figure, angles DAB and CAE are congruent. Angles DAC and BAE are also congruent.
We can solve for unknown angles using VErtical Angle Theorem by setting them equal and isolating x. To create a proof begin with what is given, followed by the VA theorem and then continue on to solve for x.
