Based on the measures provided in the diagram, determine the measure of ∠BDC. (You may assume thar point A is the center of the circle.)

A. 44 degrees
B. 46 degrees
C. 88 degrees
D. 92 degrees

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

answer: 7270
