Work out the length of AB.
Give your answer to 3 significant figures.
A=(-1,6) B=(5,3)

D = 6.71

Step-by-step explanation:

For Finding Length, we'll use the distance Formula:

=> Distance Formula =

=> D =

D =

D =

D =

D = 6.71

The length of AB is 6.71

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

answer: simile

step-by-step explanation: the difference between simile and metaphor is a simile describes with "as" and "like"
