Do you think there is a postulate or theorem for aas, aaa, or ssa congruence?

Step-by-step explanation:

The only one that has a postulate or theorem for triangle congruency is AAS.  AAA is used for similarity, not congruency; SSA is not anything.  It is the ambiguous case in triangles.  In other words, it can't be used to prove anything at all in triangle congruency or similarity.

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
