A ray is defined as a piece of a line that has one end point and the other end extends infinitely i.e., option D is correct.

Further explanation:

In geometry the three terms which are considered to be undefined are line, point and plane. From these three undefined terms the other terms in the geometry are defined.

A ray is defined as a piece of line which starts from one point and the other end extends indefinitely in the other direction.

There are four options given out of which one option is to be marked as the correct answer.

Option A:

In the option A it is given that a ray is defined as a piece of line with two end points.

The above statement which defines the ray is completely incorrect because a ray cannot have it’s both ends fixed. The piece of a line which has its both ends fixed is called a line segment.

For a ray one end is fixed and the other end extends continuously.

This implies that option A is incorrect.

Option B:

In the option B it is given that a ray is defined as a collection of all such points which are equidistant from a given point.

The above statement which defined the ray is completely incorrect because the collection of all the points which are equidistant from a given point is called circle.

This implies that option B is incorrect.

Option C:

In the option C it is given that a ray is defined as a two line segments with a common endpoint.

The above statement which defined the ray is completely incorrect because when two line segments are joined with a common endpoint it does not form a ray.

This implies that option C is incorrect.

Option D:

In the option D it is given that a ray is defined as a piece of a line that has one end point and the other end extends infinitely.

The above statement which defines the ray is completely correct because a ray has one end point and the other end extends continuously.

This implies that option D is correct.

Therefore, a ray is defined as a piece of a line that has one end point and the other end extends infinitely i.e., option D is correct.

Let’s solve where they have a triangle, so the height is 9 cm, the base is 3 cm:

1/2 • 9 • 3 = 13.5

Since there’s 2 triangles we do:

13.5(2) = 27

Now the rectangle in the middle, where the height is 9cm and the base is 12cm:

12 • 9 = 108

Add up the areas:

108 + 27 = 135

Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second
stiks02 [169]


angle 1+ angle 2=180    supplementary angles add up to 180

angle 2=x     assign angle a variable

angle 1= 3x-38      find equation for first angle

3x+x-38=180      set both angles added together equal to 180

4x-38=180        combine like terms

4x=218        add 38 to both sides

x=54.5        divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38   plug back in and solve

angle 1= 125.5
