By the external angle theorem

5x = (5x - 30) + m < RST

m < RST = 5x - 5x + 30 = 30

also m < STR = m < SRT = 5x - 30

So as there are 180 degrees in a triangle:-

5x - 30 + 5x - 30 + 30 = 180

10x = 180 +30+30-30 = 210

x = 21 answer

A construction crew is lengthening a road. The road started with a length of 59 miles, and the crew is adding 2 miles to the roa

Illusion [34]

The answer is L = 59 + 2(d). If we plug in our numbers, we will get L = 59 + 2(32). 2*32 is 64, and if you add 59 you get 123 miles.

This isn’t apart of the question, but 59 would be the y-intercept. 2 miles per day (2/1) is the slope.

Can you help me with this question.

HACTEHA [7]

For the scale factor, use the dimensions from similar sides:

Using 18 from the original image you would use 6 from the scaled image.

18 /6 = 3

This means the scaled image is 3 times smaller than the original. Because the scaled image is smaller divide 1 by the scale factor to get 1/3.

Q2:

The scale factor is 1 inch = 12 miles.

Multiply the total inches by 12:

6.5 x 12 = 78 miles.

What’s a absolute deviation

Sergeeva-Olga [200]

Answer:

Absolute deviation is when you find the mean of a data set, then the difference between each number and the mean, then the average f the differences.

Step-by-step explanation:

Maddox: |10-9| = 1

Enrique: |10-13| = 3

Gloria: |10-9| = 1

McKenna: |10-10| = 0

Asher: |10-9| = 1

Hannah: |10-9| =

Danielle: |10-10| = 0

Katy: |10-10| = 0

Timothy: |10-11| = 1

Gentry: |10-9| = 1

Now you have the numbers: 1, 3, 1, 0, 1, 1, 0, 0, 1, 1,

Now find the mean of those numbers:

$\frac{1 + 3+1+0+1+1+1+0+0+1+1}{10} =\frac{10}{10} =1$

The absolute deviation is 1.
