Similar triangles that have a scale ratio other than 1 are not congruent triangles.

The true statement about the proportions of the sides is \frac{AC}{DF} = \frac 52

The scale ratio is given as: 5 : 2

And the corresponding sides are given as:

  • AB and DE.
  • BC and EF.
  • CA and FD.

The above highlights mean that,

\frac{AC}{DF} = \frac{BC}{EF} = \frac{AB}{DE} = \frac 52

Hence, the true statement is \frac{AC}{DF} = \frac 52

the same type of television is being sold at two different stores. store A is selling the television for $800, which is $120 mor
svlad2 [7]

Answer: the selling price of the television at store B is $1360

Step-by-step explanation:

Assuming the selling price of the television at store B is represented by $B. Store A is selling the television for $800, which is $120 more than half the cost of the television at store B. The equation representing this situation is expressed as

800 = B/2 + 120

Multiplying the left hand side and the right hand side of the equation by 2, it becomes

1600 = B + 240

B = 1600 - 240

B = $1360
