X=6
16 plus 2 is 18 and divided by 3 is 6
Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)
To get the interior angles you subtract 180 from 12 to get 168 degrees
Any number is equal to that number over 1
So x is equal to x/1
Same thing with 24. 24 = 24/1
To get it into percent we multiply by 100 so:

And simplifying that we get

And x/100 = x%
so 2400/100 = 2400%
So your answer is
<em><u>2400%</u></em> :)
B because you multiply 7 times 4 that’s 28 then times 5 that’s 140 so for b you do 5 times 7 that’s 35 then times 4 that’s 140 so b is the correct answer, hope it helps
