Natalie is completing construction of an equilateral triangle inscribed in a circle, as shown below: What should be the next step in her construction? Construct a line perpendicular to the line AB to create four congruent quadrants.

Construct six equal sections around the circle using the original radius as a guide.

Construct another point C anywhere on the circle to be the third vertex of her triangle.

Draw arcs above and below line AB to show where the triangle sides meet.

Construct six equal sections around the circle using the original radius as a guide.

Step-by-step explanation:

Equilateral triangle is one which has equal sides. All of the sides and angles of the triangle are equal. Inscribed circle is formed when the sides of the triangle are tangent to the circumference of the circle. Natalie should construct six equal sections around the circle to construct equilateral triangle inscribed circle.

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
