Answer:
x=40 degrees
Step-by-step explanation:
there is 180 degrees in half a circle,and 180-100=80
and because there are 2 x values on either side you divide that 80 by 2 which gives you 40.
Answer:
1: equivalent
2: equivalent
3: not equivalent
Step-by-step explanation:
for 1 & 2, you just switch the terms, but for 3, the 6z is not negative in the first expression, but it is in the second.
