Answer:
x = 30, z = 45, y = 105
Step-by-step explanation:
The lines are straight, so:
x = 30
z = 45
y = 180 - (45 + 30)
So there
3. definition of supplementary angles
5. defintion of congruency
6. substitution <em>(refer to statements 3 and 5)</em>
Answer:
cpctc and aas
Step-by-step explanation:
If u look at it there is only 2 angles and one side (aas) and cpctc because it saying that since we know it congruent then we know that ab is equal to cb
