Hi there!

Using the formula - n-2*180 -, we know that the interior angles of a pentagon add up to 540. We can use the values we're given and add them together and set them all equal to 540, then solve.

WORK:
540 = 204 + 12x 
336 = 12x
x = 28

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

How can I convert measurements of weight? Give an example <br> ( please help)
sashaice [31]

Measurements of weight can be converted quite easily! However, you may need some extra information if you are converting from things like pounds to kilograms.

For conversions like pounds to kilograms, you will need a conversion factor. Most of the time, a quick Google search will find you this factor. For example with pounds and kilograms, 2.205 pounds is equal to 1 kilogram. To find the number of kilograms in a pound, you would divide the number of pounds by 2.205. To find the number of pounds in a kilogram, you would multiply the number of kilograms by 2.205.

For other conversions, like kilograms to grams, you would need to remember your prefixes. For example, kilo means 1000. Grams is the single unit, so that means 1000 grams is equal to 1 kilogram. To find the number of grams in a kilogram, you would multiply the number of kilograms by 1000. To find the number of kilograms in a number of grams, you would divide the number of grams by 1000.

Hope this helps!! :)
