In the diagram, bc ≅ ef and ∠a and ∠d are right angles. for the triangles to be congruent by hl, what must be the value of x? a)8 b)9 c)17 d)34

a)8

Step-by-step explanation:

4x+2=34,x=8

ED=AB=34

EF=BC(given)

angle A=angle D(given)

therefore when x=8, Tri BCA congruent Tri EFD (reason:HL)

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
