A building 62 feet tall costs a shadow 21 meters long. At what angle is the sun shining on the building ?

18.71

Step-by-step explanation: you use tangent because you are given the opposite and adjacent lengths. The you use inverse tangent to solve for theta.

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
