2y° + x° + y° + 2x° + (180-33)° = 360°

3x + 3y + 147 = 360

3(x+y) = 360 - 147

3(x+y) = 213

x+y = 71

2y + 2x + K = 180

2(x+y) + K = 180

2 *71 + K = 180

142 + K = 180

K = 38°

the last one

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

are you an artist's daughter? cuz dang you a fine piece of art, girl.
