Answer:

1. Given

2.corresponding angles in similar triangles are congruent

3.Ratio of corresponding sides of similar triangles is the same

4. DC/AE =1/3

5. 1/3 ratio of corresponding sides of similar triangles is the same

6. Triangle ABE is similar to triangle DBC

Step-by-step explanation:

Similarity in geometry requires states that when the measure of corresponding sides of two triangles, the two triangles are similar.

In this case, according to the SSS similarity, if the corresponding sides of two triangles are proportional, the triangles are similar. For example, BC/EB=BD/BA=1/3

A rectangle length was 4 feet longer than triple the length of it width

wlad13 [49]

Length is 48 ft

The perimeter of a rectangle is equal to the sum of all side’s.
2(lengths)+2(widths)= perimeter
Length=3x+4
Now given the perimeter of 140
3(3x+4)+3(x)=140
9x+12+3x=140
12x+12=140
12x=128
X= 10.7
10.7 is the width

Length=3x+4
Length =3(10.6)+4
Length=31.8+4
Length=35.8
Answer = 35.8
This can only be answered if you were given a perimeter.

sammy [17]

Answer:

$110 and $30

Step-by-step explanation:
