Answer:
x=123
Step-by-step explanation:
x is across from the angle that measures 123 degrees. Therefore, they are vertical angles, and are congruent.
x=123
Additionally, 57 and x are on a straight line. This means they are supplementary and add to 180 degrees
57*x=180
Subtract 57 from both sides to get x by itself.
x=123

It’s A. Since every aspect of that is multiplication, you can change around how you write it such as (6*7)^3. 6*7 is 42, and 42^3 is the exact same as 42^3
