Question

The Sum of the angle measures of the polygon is 540 degrees. Write and solve an equation to find the value of X.​

Answer 1

Answer:

Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.

Step-by-step explanation:

Here is an explanation of what happens to the balloon when inflated by blowing air into it.

• Blowing up a balloon requires forcing additional air particles from our lungs into the balloon. These particles bumped the balloon’s inside walls, creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.
• The collision of these air particles with the walls generates a high-pressure environment inside the balloon relevant to the atmospheric pressure around it. This is why when a balloon is released; the high-pressure air flows out of the balloon to the low-pressure air surrounding it: ‘Winds blow from high to low.

Answer 2

139° + 3x + (5x-10)° + (10x-9)° + 3x° = 540°

=> 21x + 139 - 19 = 540°

=> 21x = 540 - 120

=> 21x = 420

=> x = 20
