Answer:
D
Step-by-step explanation:
You can already knock out the first two because you cant have negative feet. If you line the vertex (1) with the parabola, you can see that the vertex lines up with 16. You round that up and your answer should be 20
Answer:
x = 18
y = 54
Step-by-step explanation:
A straight line equals 180 degrees.
Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.
Because there is a right angle, we can subtract 90 -72 = 18.
18 + 2x = 3x
18 = x
A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.
