The angles should add up to 180. 48 + 81 = 129
180 - 129 = 51
2 sides need to be equal. 25 + 25 = 50
Now solve for b.

Answer:
A. By SAS only
Step-by-step explanation:
Side Side Side postulate (SSS) states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Side Angle Side postulate (SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
In triangles ABC and AED:
- sides ACand AD are congruent (from the diagram);
- angles BCA and EDA are congruent (given);
- sides BC and ED are congruent (from the diagram).
So, SAS postulate can be applied.
SSS postulate cannot be applied, because it is not given that sides AB and AE are conruent.
