Use δabc below to answer the question that follows:

which fact is not used to prove that abc is similar to dbe?

the sum of angles a and b are supplementary to angle c.

segments ac and de are parallel.

ab is a transversal line passing ac and de.

angle b is congruent to itself due to the reflexive property.

Two triangles can be similar by AAA,ASA ,SSS ,SAS property of similarity.

To prove triangles ABC  similar to DBE  we consider

Segments AC and DE are parallel.

AB is a transversal line passing AC and DE.

Angle B is congruent to itself due to the reflexive property.

The option which is not used to prove that ABC is similar to DBE is the first option :

The sum of angles A and B are supplementary to angle C.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
