Answer:
B
Step-by-step explanation:
Those lines both make up the tip of the triangle figure...
The first thing we must do is calculate the circumeference:

now, calculate the angle of arc
360° = 49.612
360° - 66.4° - 180° = x
x = 113.6°
now, to calculate the arc length it would be:
4/5 because look at the picture
The equation of the parabola whose focus is at (7, 0) and directrix at y = -7 is
(x-7)^2 = 14(y + 7/2)
Hope this helps
