PLEASE HELP!! WILL MARK BRAINLIEST AND THANK YOU!!! X= ___________

Mathematics
1 answer:
Harman [31]3 years ago
5 0

Answer: x=26

Step-by-step explanation:

When parallel lines are cut by a transversal several angles are formed.

A pair of non-adjacent angles located outside the parallel lines and on opposite sides of the transversal are called  "Alternate Exterior angles".

By definition, they are congruent, which means that they have equal measure.

In this case, you can identify that (5x+7)\° and (8x-71)\° are Altermate Exterior angles.

Then, you can write the following equation:

5x+7=8x-71

Finally, you must solve for "x" in order to find its value. This is:

7+71=8x-5x\\\\78=3x\\\\x=26

Being that the triangle has a center of dilation at (0,0) you must contract the points towards (0,0). The scale factor is 1/3 so you must divide the difference in location of the points on the X and Y axis by a scale of 1/3.

1/3 of 9 = 3 , y = 3

1/3 of -6 = -2 , x = -2

by changing these points a new triangle will be formed

What is 2.5 x 7/10 =? and how did you get the answers?
Ivan

Answer:

1.75 or  \frac{35}{2}

Step-by-step explanation:

2.5 * 7/10 is just like 2.5 * 0.7

so 2.5 * 0.7 = 1.75

You could also convert 2.5 to fraction which is 25/10

so you would have \frac{25}{10} * \frac{7}{10} = \frac{175}{100} reduced would  equal \frac{35}{2}

How this helps you! :)

Could you please mark this answer as brainiest?

It would help me!

Thank you!
