Help me please, and thank u

Step-by-step explanation:

Check the attached diagram... since they are parallel lines, those angles should be equal. now as per the theorem of opposite angles, (3x + 10)° should be equal to 70° .

(3x + 10)° = 70°

3x = 60°

x = 20

y²=20x

Step-by-step explanation:

Note: I'm assuming you mean x=-5 for the directrix because what you're asking isn't possible

Since we are given a horizontal directrix, the parabola must also be horizontal.

Horizontal Parabola:

(y-k)² = 4p(x-h)

Vertex: (h, k)

Focus: (h+p, k)

Directrix: x = h - p

Since the focus of the parabola is (5,0), then k=0 and h+p=5. We also know that since the directrix is x=-5, then -5=h-p. If we set these equations equal to each other, we can solve for h and p:

h+p=5

h-p=-5

2p=10

p=5

Since p=5, then h=0. Therefore, we have for our equation of the parabola:

(y-k)² = 4p(x-0)

(y-0)² = 4(5)(x-0)

y²=20x
