A horizontal slice through a three-dimensional solid produces the two-dimensional shape below. (The shape is a square)
​Which one of the following solids produces this two-dimensional shape when sliced horizontally?
Is it A, B, C, or D????

Answers

Answer:

C

Step-by-step explanation: i am doing same thing you are doing rn

You can use the fact that a horizontal slice is like you're slicing the given shape parallel to ground.

The correct shape which will produce a square when sliced horizontally is  ""D" figure which as 4 sides.

What is a square?

A square is a closed figure formed by end to end joined equal length four line segments such that all the adjacent lines are perpendicular to each other.

A square has 4 sides.

What is horizontal slicing?

Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.

When you slice an object horizontally, you cut it parallel to ground.

How to know which of the given solid will produce square?

Since a square has 4 equal sides, all perpendicular to each other, we see that only 4th object has 4 sides.

Thus, the fourth solid, named D is the solid that can produce square when sliced horizontally.

The answer is 98 degrees for y

Answer:

Step-by-step explanation:

First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180

For the triangle on the left, sum up the angles and set it to 180 degrees.

60 + 38 + x = 180

x = 82 degrees

Now solve for y by doing this

82 + y = 180

y = 98 degrees

While I'm here, Ill solve for z because it will most likely ask in the next question.

26 + 98 + z = 180

z = 56 degrees

-2 1

-1 -1

2 -7

Step-by-step explanation:

If x = -5, then:

y = -3 -2(-5)

y = -3 + 10

y = 7

If x = -2, then:

y = - 3 -2(-2)

y = -3 + 4

y = 1

If x= -1, then:

y = -3 -2(-1)

y = - 3 + 2

y = -1

If x=2, then:

y = -3 -2(2)

y = -3 -4

y = -7

Triangle ABC is transformed to triangle A′B′C′, as shown below: A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0. Which equation shows the correct relationship between the measures of the angles of the two triangles? The measure of angle CAB = The measure of angle C prime B prime A prime The measure of angle BCA = The measure of angle A prime B prime C The measure of angle CAB = The measure of angle C prime A prime B prime The measure of angle BCA = The measure of angle C prime A prime B prime

Answers

Answer:

The measure of angle BCA = The measure of angle C prime A prime B prime

Step-by-step explanation:

The correct relationship between the measures of the angles of the two triangles is;

The measure of angle BCA = The measure of angle C prime A prime B.

Given that

Triangle ABC is transformed to triangle A′B′C′, as shown below:

A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes.

A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.

A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.

We have to determine

Which equation shows the correct relationship between the measures of the angles of the two triangles?

According to the question

Triangle ABC is transformed to triangle A′B′C′, as shown below:

Here the triangle ABC is similar A'B'C' are similar triangles.

For similar triangles angles are congruent.

A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.

A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.

Therefore,

<BAC = <B'A'C'

<ABC = <A'B'C'

<ACB = <A'C'B'

Hence, The correct relationship between the measures of the angles of the two triangles is The measure of angle BCA = The measure of angle C prime A prime B.
