For this case we have that by definition, a flat angle is the space between an intersection between two lines whose opening measures 180 degrees.
Then, if we look at the figure we have to:
Thus, the angle ABC is , less than 90 degrees, so it is an acute angle.
The CBD angle is8, greater than 90 degrees, so it is an obtuse angle.
ANswer:
ABC is acute angle
CBD is obtuse angle

Answer:
The last choice is the one you want
Step-by-step explanation:
First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward. The first and the third parabolas are negative so they open upside down. That leaves us with choices 2 and 4. We find the side to side and up or down movement by finishing the completion of the square that has already been started for us. Do this by factoring what's inside the parenthesis into a perfect square binomial.
The second one factored becomes:
which reflects a shift to the right 3 and up 1. Not what we are asked to find.
The fourth one factored becomes:
which reflects a shift to the right 3 and down 5. That's what we want!
