Find the measure of arc VF. (look at the picture provided) please help

60degrees

Step-by-step explanation:

Using the theorem that states that angle at the vertex is half the difference of the angles at the intercepted arcs

Angle at vertex can be gotten by taking the difference of 119 and 65

Angle at the vertex = 119 - 65

Angle at the vertex = 54

Hence;

54 = 1/2(168-VF)

Cross multiply

54  * 2 = 168-VF

108 = 168 - VF

VF = 168 - 108

VF = 60degrees

Hence the measure of arc VF is 60degrees

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

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
