Answer:

1) x = 19

2) x = 24 1/3

Step-by-step explanation:

1) there are 360 degrees in a 4-sided polygon

90 + 90 + 4x - 14 + 5x + 23 = 360

9x + 9 = 180

9x = 171

x = 19

2) there are 720 degrees in a 6-sided polygon

since this hexagon is 'regular' then all angles are equal and measure 120°

6x - 26 = 120

6x = 146

x = 24 1/3

AlexFokin [52]

ANSWER: The length of the entire dash is 700 meters.

EXPLANATION:

Because 20% of the dash equals 140 meters, we can use a variable to figure out the length of the entire dash.

Let x be the length of the entire dash.

$.2x = 140\\\\x = 700$

The length of the entire dash is 700 meters.
