Find the value of x. Round the length to the nearest tenth. The diagram is not drawn to scale.

For the given triangle, the value of x is 2,880.2 m.

Step-by-step explanation:

Step 1:

The sum of the angles on a straight line is 90°. It is given that the sum of the upper sides angle and 10° is 90°.

So the triangle has an angle of 80° on the top side.

Step 2:

For the top side, the hypotenuse measures x m and the adjacent side measures 500 m.

To determine the value of x, we determine the cos of the given angle.

So rounding this off, we get the value of x is 2,880.2 m.

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
