Use the area of the rectangle to find the area of the triangle. 4 ft
8 ft
O A. The area of the triangle is 16 square feet, because the
area of the rectangle is 16 square feet.
B. The area of the triangle is 16 square feet, because the
area of the rectangle is 32 square feet.
O C. The area of the triangle is 32 square feet, because the
area of the rectangle is 32 square feet.
O D. The area of the triangle is 14 square feet, because the
area of the rectangle is 28 square feet.

answer: the area of the parallelogram below is 42 square meters.

i believe that the slope of the line is -5

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
