Here's the second one  [  again, to the best of my ability ]

 

5.  Reflexive Property  (Common Angle)

6. ΔBDC  similar to ΔBCA

7.  BC/BD   =  BA/BC.....

So... by  Substitution.....  a / x  = c / a ...Corresponding Parts of Similar Δs are Proportional

8. Cross- Product Equality

9. Congruency of Right Angles

10. Reflexive Property (Common Angle )

11.  ΔADC  similar to ΔACB

12. AC/AD   =  AB/AC.....

So... by  Substitution.....  b / y  = c / b ...Corresponding Parts of Similar Δs are Proportional

13. Cross - Product Equality

14. Substitution

15. a2 + b2 =  c (x + y)

16. Segment Addition Postulate

17. Substitution
