Answer:

Step-by-step explanation:

all triangles angles add up to 180, add up the other 2 sides, then subtract from 180, 130, which means because of how triangles work, the other side must make it equal to 90, so 130+50=180.

Answer:

The correct answer is choice D.

Step-by-step explanation:

Since the parabola opens sideways, that means the function will feature $y^2$ and not $x^2$ , so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of $y^2$ is positive. Using all of this information, you'll find that the correct answer is D: $x = \frac{1}{12} y^2$ .
