Answer:
Step-by-step explanation:
1. All triangles add up to 180°, so you can make an equation like this:
[tex]60.8+57.1+A=180\\117.9+A=180\\A=62.1[/tex]
2. As for which angle corresponds to ∠A, we know that ∠A is across from ∠B which is 60.8°. We know that in the other triangle, ∠Z=60.8° as well and ∠Y is right across from it. Therefore, ∠Y corresponds to ∠A.
3. It would be useful to know the options you have for this one. I'd say they're similar (if that's an option).
