I need help on this one plzzz

Step-by-step explanation:

1. m∠ EFH = 180° - 67°

= 113°

2. x + 40° + 67° = 180°

x + 107° = 180°

x = 180° - 107°

= 73°

y=mx+b

step-by-step explanation:

m slope, b y-intercept

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
