Two cargo ships spot a signal fire on a small island. The captains know they are 140 feet
away from each other and using angle measuring device they can determine the angle from
cach of their ships to the signal fire. The angle at ship A is 82º and the angle at ship B is 78°.
How far is it from Ship B to the signal fire at point C?
Hint: Use Law of Sines:
sin A = sinB = sin C
82
B
a.
b.
48.9 feet
400.4 feet
c. 405.3 feet
d. 673.4 feet

Step-by-step explanation:

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
