Answer:

Option B is the right answer.

Step-by-step explanation:

A parabola is part of a conic section which is got by cutting a right circular cone by a plane, when the intersection gives rise to an open figure.

A parabola is defined as one conic section with eccentricity 1.

Eccentricity is defined as the ratio of distance of the curve from a line to the distance from a point.

In parabola, the line is the directrix, and the point is the vertex.

And always in a parabola, the distance from the directrix will equal the distance from vertex

Hence option b is right.

Answer:

  • x = 85°

Step-by-step explanation:

<u>Sum of interior angles of any triangle is 180°:</u>

  • 52° + 43° + x = 180°
  • 95° + x = 180°
  • x = 180° - 95°

Find the missing length indicated <br> A) 25<br> B) 5<br> C) 8<br> D) 3
Nonamiya [84]

Given:

The figure of a triangle.

To find:

The missing length.

Solution:

Let x be the missing length.

Basic proportionality theorem(BPT): According to this theorem, if a line is parallel to the one side of a triangle then that the line intersects the other two sides of the triangle in the same ratio.

Using Basic proportionality theorem, we get

\dfrac{6}{8-6}=\dfrac{12-x}{x}

\dfrac{6}{2}=\dfrac{12-x}{x}

3=\dfrac{12-x}{x}

3x=12-x

Adding x on both sides, we get

3x+x=12

4x=12

x=\dfrac{12}{4}

x=3

The missing length is 3 Therefore, the correct option is D.
