Me , i'll choose a brainiest ! which trigonometric ratios are correct for triangle abc? check all that apply. sin(c) = square root 3/2 cos(b) = square root 2/3 tan(c) = square root 3 sin(b) = 1/2 tan(b) = 2 square root 3/ 3

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
