The answer is 156 after multiplying 12•12 getting 144 then adding 12 to get my answer.
Answer:
Congruent angles have the same angle.
Answer:
Yes, you can conclude that ΔJKL ≅ XYZ.
Step-by-step explanation:
I forget how to describe it in geometric terms but, if you read the similarity statement again, and follow each angle, you'll notice that the shapes match, and they correspond to each other, it would be different if it said something like ΔLKJ ≅ XYZ because it does not match.
If you're looking for a specific reason, we'd say that they're congruent because of SAS (Side-Angle-Side)
If this still confuses you, hit me up.
Drop parentheses -7a-19c+12a+30c+21a-11a
Combine like terms -18a-19c+33a+30c
Combine like terms (again) 15a+11c
Simplified, this expression is 15a+11c
