Answer:
IM SMART
Step-by-step explanation:
1) False
2) True
3) True.
You can see for number one the angles are not the same, therefore they are not equal to eachother.
For two, because the line EC is running flat it is equal to 180. Because their is a little box on the other side of 1 & 2, we know that is equivalent to 90 degrees. Therefore the other side (1 &2) HAS to be 90, because the line in which they are on is 180, 90+ 90 = 180.
3, The same type of math for #2
9-16x^2
This is the answer pretty much the 3 is okay but once you see the four notice there’s - and + you’d multiply it
