Which postulate or theorem proves that these two triangles are congruent? a. asa congruence postulate b. sas congruence postulate c. hl congruence theorem d. aas congruence theorem i think it's either a or d.

A. ASA Congruence Postulate

Step-by-step explanation:

We have marked that ∠BAE and ∠CDE are congruent.  We also have marked that AE and ED are congruent.  

∠AEB and ∠CED are also congruent; this is because they are vertical angles.  Vertical angles are opposite angles that share only a vertex; these are vertical angles and thus are congruent.

This gives us two angles and an included side; this gives us ASA.

7 units

Step-by-step explanation:

The x is the same, so find the difference in y.

3 - -4 = 7
