Use the diagram to choose all the true statements about the isosceles trapezoid. Group of answer choices

AB = CD

AC = DB

Triangle ABD congruent to triangle BAC

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

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
