Which of the following correctly completes the proof of the isosceles triangle theorem? A.) SAS
B.) SSS
C.) ASA
D.) AAA

hi, i am not sure about this one but i think its d,

hope this !

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

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
