Answer:
a and b bc that are in the negative-positive quad
The question is impossible to answer. as we do not have the image of the polygon
Complementary angles add up to 90 (there should be a right angle in the diagram)
x+20+x+10 needs to equal 90 where x=30
Left angle is measured 30+20=50 degrees
Angle on the right is measured 30+10=40 degrees
Answer:
For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.
Step-by-step explanation:
For example, x > 2 would have an open circle and you are NOT including the 2 that is inputted.
For x 
6, it would have a closed circle and you ARE including the 6 that is inputted.
