Find the value of x. Then find the measure of each labeled angle
Artyom0805 [142]

Step-by-step explanation:

Question 10 :

3x + 6 = 4x – 12 ( reason: corresponding angles due to parallel lines)

simplify and get x, thus x = 18

to find 3x + 6 or 4x - 12(which is both the same),

3(18) + 6 = 60° , 4(18) - 12 = 60°

Question 11:

2x + 24 + x = 180 ( reason: interior angles due to parallel lines)

simplify again to get x, you will get x = 52

then find the individual by subbing in the value of x into the equation.

so 2x + 24 = 2(52)+24 = 128° and x = 52°

Find the mean, median, and mode 77, 92, 80, 92. Please explain how you got your answer.​
vaieri [72.5K]

Answer:

The mean is 85.25

The medium is 86

The mode is 92

Step-by-step explanation:

The mean is all the numbers added divided by the number of values.

77 + 92 + 80 + 92 divided by 4

341 divided by 4 = 85.25

The median is the middle number

92 + 80 divided by 2

172 divided by 2 = 86

The mode is the number that occurs the most which is 92.

If the length of a rectangle is x-2 and its area is 2x3 – 8x2 + 2x+12, it’s width would be what?
hram777 [196]
Width would have to be a quadratic
Use long division to find the other factor of the cubic polynomial P (x).
P (x) factors in case it is reducible over R[x]
if it weren't then P (x) mod R [x] would be a field
otherwise you could use the Eisenstein Criterion.

A side of the triangle below has been extended to form an exterior angle of 129°. Find the value of x.
Anvisha [2.4K]

Answer:

The value of x is 30°

Step-by-step explanation:

X° + 90° = 129° (Exterior angle property)

x° = 129° - 99° = 30°

<u>x°</u><u> </u><u>=</u><u> </u><u>3</u><u>0</u><u>°</u>

Hope it helps:)
