Answer:

Step-by-step explanation:

You cannot find the exterior angles of any irregular nonagon. If it is a regular one, then you can. A regular nonagon has 9 sides and so 9 exterior angles all of which are equal to 360/9 = 40 degrees. The interior angle = 180 - 40 = 140 degrees.

Answer:

Option D) 15%

Step-by-step explanation: 10.5/70= .15

.15x100=15

It would be easier to think it through if instead for 70 we took the number 100. Lets reword it and say what percent of 100 is 38? This would be easy to answer it would be 38% But how you check it is, you take 38 and divide by the total (100) which is .38 then multiply by 100 you will get 38% Same with your equation take the 10.5 and divide by the total amount which is 70 you will get .15 then multiply by 100. the answer will be 15%
