HELPP PLSSS ! Is the graph below Arithmetic ? Please explain why or why not!! I’m giving 40 points btw

sorry, i don't know i just need points, i'm new here. chao

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

x = 3

step-by-step explanation:

you haven't given us any choices but we can guess.

-35x = - 105       divide by - 35

-35x/-35 = -105/-35   the minus signs cancel out and 105 can be divided evenly by 35

x = 3
