Answer:

The number is equal to 83.18

Step-by-step explanation:

In order to find this number, we need to turn the words into numerical statements.

-90 times the difference between a number = -90(x - 83)

the number plus -99 = x + -99

Now we can set them equal to each other.

-90(x - 83) = x + -99 -----> Distribute

-90x + 7470 = x - 99 ----> Add 90x to both sides

7470 = 91x - 99 -----> Add 99 to both sides

7569 = 91x ------> Divide by 91

83.18 = x

Well what you would have to do is look for numbers that are easy to divide. For example, lets try 9000/10, and so the answer would be 900 and so if you divide the actually numbers, you could compare them, and see if 900 would be a reasonable.

Never true. Vertical angles are equal to each other, not adjacent to each other.

Answer:

<h2>Reflection.</h2>

Step-by-step explanation:

The image attached shows a representation of the problem, there you can observe the congruence between triangles.

Also, using the images you can easily deduct the transformation we need to map one triangle onto the other one, we just need to reflect one triangle across and axis that pass through point M, such line acts like a mirror.

Therefore, the right answer is reflection.
