Answer:

18 will be the number of sides.

Step-by-step explanation:

As we know that the sum of exterior angles of a polygon is 360°.

The formula is:

  • The exterior angle of a polygon = 360 ÷ number of sides

As each exterior angle of a regular polygon is 20°.

so putting the value exterior angle 20° in the formula

The exterior angle of a polygon = 360 ÷ number of sides

                                               20  = 360 ÷ number of sides

                                               20  = 360/number of sides

so the number of sides will be:

                         number of sides = 360/20

                                                     = 18

Therefore, 18 will be the number of sides.

U-8.1 = 6.35 what does u=
Nesterboy [21]
Since U is being subtracted by 8.1, we can assume that if we added 8.1 to both sides, it should equal U

U - 8.1 = 6.35      
              To make it equal to U, we have to add 8.1 to both sides

The answer is,

U = 14.45

Solve for x. <br><br> 16 = -2x - 1<br><br> x = -8<br> x = -7<br> x = 7<br> x = 8
ioda

I tend to flip so x is on the left, so:

-2x - 1 = 16

-2x = 17

x = -17/2, which is -8.5

Rounding up, your answer would be x = -8 !
