Triangle ABC is similar to triangle DEF which proportion can be used to find the length of DE in centimeters?

A. 4/3 = DE/9

B. 5/15 = DE/4

C. 4/DE = 9/3

D. 9/DE = 3/5

means if you're already damaged some way when you take out a medical insurance you will not get full compensation for that injury that you already have.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says
