SAS property.

Step-by-step explanation: The problem gives you the value of two sides and an angle that these two sides share. Based on these values, you can use the SAS angle property to prove they are similar. The SAS property, as its name states, is a property that proves that two triangles are similar if two of their sides have a common ratio (in this case, their common ratio is 1:2) and one angle these two sides share is congruent to the other (in this case, shared angle A and D are congruent).

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
