Use a paragraph, flow chart, or two column proof to prove the angle congruency

 see proof below

Step-by-step explanation:

   Statement                          Reason

1. ∠CAX ≅ ∠ BAX               1. Given

2. AC ≅ AB                        2. Given

3. AY ≅ AY                        3. Reflexive Property

4. ΔCAY ≅ ΔBAY              4. SAS Congruency Theorem

5.  CY ≅ BY                       5. CPCTC

6. ∠CYA ≅ ∠BYA              6. CPCTC

7.  ∠CXY ≅ ∠ BXY             7. Given

8. ΔCYX ≅ ΔBYX              4. AAS Congruency Theorem

9. ∠XCY ≅ ∠XBY              9. CPCTC

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

answer: it is 8

step-by-step explanation:

you know why its 8
