$767.00
$665.00
$617.50
$613.60

$613.60.

Step-by-step explanation:

Given : Rebecca Whitaker purchased a new flat screen television for $767.

To Find: She made a 20% down payment and financed the remainder.

Solution:

Cost of flat television = $767

She made a 20% down payment.

So, Down payment =

                                =

                                =

So, Payment left =

                           =

We are given that she financed the remainder.

So, She financed $613.60.

The method for figure 1 is SSS.

The method for figure 2 is AAS.

The method for figure 3 is ASA.

The method for figure 4 is AAS.

Step-by-step explanation:

In figure 1, two corresponding sides are equal and one sides is common. It means all corresponding sides are congruent.

By SSS postulate, both triangles are congruent.

Therefore the method for figure 1 is SSS.

In figure 2, two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle.

By AAS postulate, both triangles are congruent.

Therefore the method for figure 2 is AAS.

In figure 3, two angles and included side of one triangle are congruent to the corresponding parts of another triangle.

By ASA postulate, both triangles are congruent.

Therefore the method for figure 3 is ASA.

In figure 4, two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle.

By AAS postulate, both triangles are congruent.

Therefore the method for figure 4 is AAS.
