3b^2 - x = -9b^2
x = 3b^2 +9b^2
x = 12b^2
3b^2 -12b^2 = -9b^2
hope this will help you

Answer:
Step-by-step explanation:
From the figure attached,
In the given right triangles ΔADB and ΔCDB,
Statements Reasons
1). ∠BAD ≅ ∠BCD 1). Given
2). BD ≅ BD 2). Reflexive property
3). ΔADB ≅ ΔCDB 3). By LA theorem of congruence of right triangles
Therefore, there is sufficient information to prove the ΔADB and ΔCDB congruent.
Leg-angle theorem (L-A) will be used to prove the right triangles congruent.
