Given m||n find the value of x.

Mathematics
1 answer:
Marina CMI [18]3 years ago
5 0

Answer:

x =17

Step-by-step explanation:

The angles are supplementary so they add to 180

6x-20 + 6x - 4 = 180

12x -24 = 180

Add 24 to each side

12x-24+24 = 180+24

12x = 204

Divide by 12

12x/12 =204/12

x = 17

How do you find the percent of a whole number?
Ostrovityanka [42]
A percentage figure shows that the quantity of parts per one hundred a segment sum compares to. For instance, "85 percent" is another method for saying "85 sections for each 100." To calculate a percentage, the entire sum must be known,  in addition to the percentage or portion amount.
