The required additional information required to prove the Triangles congruent are :

The Triangles will be congruent by HL congruency.

The Triangles are congruent by LL congruency.

The Triangles are congruent by HA congruency.

The Triangles are congruent by LA congruency.
B is 5, you can solve this by first finding the value of a, which is 2, and then plug it into the other equation. 8+2=10 so we must also make the other side 10. We then do 10-5=5, 5 is the value of b
