3.1 is like a example when it is hiding a zero behind it and you find this when you do a math problem and you don't put zero in front of a number like 100-89 you don't write "011" so that is why it is like that
Answer:
y=107
x=73
z=73
Step-by-step explanation:
y and 107 are vertical angles, which means that they're the same value because they're vertically across from each other.
107 and x are supplementary angles, so x=180-107 or 73.
x and z are also vertical angles, so x=z=73.
I think the second one does
Answer:
No, They are not equivalent
Step-by-step explanation:
The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.
The variable in this question is x.
To prove this, we equate both expressions:


This shows that they have the same value ONLY when x is 1.
This is why Andre says that they are equivalent, but they are not.
