How do you prove that vertical angles are congruent?

If they're the same, then they are congruent. If they're on an image, you can use angles in parallel lines, such as Z (alternate) angles, F (corresponding) angles, or vertically opposite angles to show that they are equal. I hope this helps! Let me know if you need further explanation :)

When two lines intersect to make an x, angles on opposite sides of the X are called vertical angle. and both angles are equal, give me a second and i will give you an example.

Describe one error that was made in the preparation of the

pashok25 [27]

Answer:

the axis labels are inconsistent with the graph title

Step-by-step explanation:

The independent variable is described as "% protein digested", and the dependent variable is described as "time." The graphed values suggest that these are reasonable descriptors for the data being plotted.

The title, however, says the data points are "percentage digestion per hour". This is in disagreement with the axis labels, and is inconsistent with the shape of the curve. (If the title is to be believed, the digestion rate is such that more than 100% of <whatever> has been digested after 10 hours.)

<em>Additional comment</em>

Another error is the vertical axis is graduated as though it were linear, but it is decidedly non-linear. Equivalent distances on the graph are shown for differences of 10%, 5%, 10% and 25%. That is the scale varies by a factor of 5 from one part of the graph to another.

ABC has coordinates of A(-8,-8) B(4,-2) C(2,2). Find the coordinates of its image after the dilation centered at the origin with

garri49 [273]

Answer:

A' ( -12 , -12 )

B' ( 6 , -3 )

C' ( 3 , 3 )

Step-by-step explanation:

To find the coordinates of a point after a dilation simply multiply the x and y values of the points by the scale factor

Points: A(-8,-8) B(4,-2) C(2,2)

Scale factor: 1.5

Coordinates after the dilation

A' = (-8,-8) --------> (-8 * 1.5 , -8 * 1.5 ) ------------> (-12 , -12)

B' = (4,-2) ---------> (4 * 1.5 , -2 * 1.5) -----------> (6 , -3 )

C' = (2 , 2) ----------> (2 * 1.5 , 2 * 1.5) -----------> (3, 3)

So inclusion the coordinates of ABC after a dilation centered at the origin with a scale factor of 1.5 are A' ( -12 , -12 ) B' ( 6 , -3 ) C' ( 3 , 3 )

Which two days had a ratio of 2:5 computers sold? Looking for brainliest.

Marianna [84]

Answer: A. Wed to Fri

We have a bunch of natural numbers and we're told a pair is in the ratio 2:5.

For natural numbers to have this ratio, the left number will be a multiple of two and the right number will be a multiple of five.

Our only option for a multiple of 5 is 15, Friday. So we have

2:5 = x:15

and x = 15*2/5 = 6

which was Wednesday's number. So we get Wed:Fri=6:15=2:5.
