If mangle upper a upper o upper c= 85°, mangle upper b upper o upper c = 2x + 10, and mangle upper a upper o upper b = 4x – 15, find the degree measure of angle upper b upper o upper cand angle upper a upper o upper b. the diagram is not to scale.
angle upper a upper o upper c is shown. point b is located on the interior of the angle in between upper a and upper c. ray upper o upper b is drawn.
a. mangle upper b upper o upper c= 30°; mangle upper a upper o upper b= 55°
b. mangle upper b upper o upper c= 40°; mangle upper a upper o upper b= 45°
c. mangle upper b upper o upper c= 45°; mangle upper a upper o upper b= 40°
d. mangle upper b upper o upper c= 55°; mangle upper a upper o upper b= 30°

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
