Answer: Option D is correct.
Step-by-step explanation:
Since we have given that
focus = (-5,5)
and a directrix y= -1
Since, equation of parabola in this case will be
Now, here
So equation will be
So, option D is correct .

2 answers:
Answer:
180°
Step-by-step explanation:
The sum of the measures of the interior angles formed by the boundary of this team pennant.
The shape of pennant is similar to triangle. It means pennant has 3 sides and 3 angle.
It would be triangle. As we know, the sum of measure of interior angles of a triangle is 180°
∠1 + ∠2 + ∠3 = 180°
Hence, The sum of measure of angles formed by boundary of pennant is 180°
