Which information would be sufficient to prove quadrilateral blue is a parallelogram?

(A)

Step-by-step explanation:

Given: BLUE is a quadrilateral.

To prove: Quadrilateral BLUE is a parallelogram.

Proof: By the definition of parallelogram, the opposite sides of the parallelogram are equal and parallel.Thus, we have to prove that the opposite sides of quadrilateral BLUE are equal and parallel.

Now, (BL and EU) and (BE and LU) are the opposite sides of the parallelogram BLUE, thus all we need is to prove that BL║EU ..

Therefore, Option A  is correct.

2 is the final ! : )

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
