Answer:
∠COA = 160°
Step-by-step explanation:
The angle intercepted on opposite side of the circle from an ARC has a measure of HALF of the Arc.
∠CBA is HALF of the ARC CA
∠CBA is given as 80°
So Arc CA is 80 * 2 = 160°
Now,
∠COA is an intercepted angle that is at the CENTER. This angle has same measure as the Arc it is intercepted from (Arc CA).
Hence,
∠COA = Arc CA
<u>∠COA = 160°</u>
Answer:
False
Step-by-step explanation:
The coefficients (numbers in front) don't matter, but the exponents do.
Like terms have exactly the same exponents on the same variables.
are not like terms.
Example: 
<u>are</u> like terms--same exponents on the x's, same exponents on the y's.
