Need math genius. forgot to post question lol. but plz

150

Step-by-step explanation:

To find the measure of an interior angle of a regular dodecagon we use the formula : Sum = (n-2)180

There are 12 sides in this polygon. The "n" represents the number of sides in the polygon.

Sum = (n-2)180

= (12-2)180 = 10(180) = 1800.

But this the TOTAL amount of interior angles in this polygon. We only have to find 1. Like I said, there are 12 sides in this polygon and tofimdkne side we divide by 12.

1800 ÷ 12 = 150

correct answer:

i^31 = -i

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
