Triangle congruence and similarly (picture included) SAS, ASA, SSS, or AAS?

Answers

Answer:

SAS

Step-by-step explanation:

SAS Postulate: "If two sets of corresponding sides on two triangles and there included angle are congruent, then the triangles are similar".

We see that line segments XY-ST and XZ-SR are congruent along with the included angles X and S. Therefore, we can justify that SAS fits the situation.

Aregular hexagon is dilated by a scale factor of 0.4 to create a new hexagon. The perimeter of the new hexagon is 0.4 times the perimeter of
the original hexagon
O True
False

Answers

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.

A triangle has one angle that measures 61 degrees, one angle that measures 44 degrees, and one angle that measures 75 degrees. what kind of triangle is it?
choices
1.right triangle
2.obtuse triangle
3.acute triangle

Answers

It is an acute triangle because none of the angles are 90 degrees or higher

Answer:

Acute triangle

Step-by-step explanation:

All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.

If any one of the three angles is 90, then it is right triangle.

If any one of the three angle is more than 90, then it is obtuse triangle.

what is the slope of 2x-4y=5

Answers

the slope is 1/2x and the y intercept is -5/4

Answer:

1/2 or .5

Step-by-step explanation:

Hey There!

So the first step of this problem is to get y on one side and everything else on the other side

to do so we use inverse operations

so to get rid of the 2x we subtract 2x from each side

we would end up with -4y=5-2x

now want to get rid of the -4 on the y

to do so we would divide each side by -4

we would end up with

[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]

so we can conclude that the slope is 1/2 or .5

Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21 and members pay only $2.50 to rent each video. For what number of videos is the cost the same?

Answers

Answer:

You need to rent

videos, and you'll pay the same amount for both. Renting

will make the membership a better method of payment.

Explanation:

We can create an equation. Say the number of videos you rent is given by

. We can write that, if we rent

videos without membership, we'll have to pay

. If we rent the same amount of videos with membership, we'll have to pay

2.5

To find the value of

such that the amount you pay without membership is equal to the amount you pay with, we write:
