An irregular parallelogram rotates 360 degrees about the midpoint of its diagonal. how many times does the image of parallelogram coincide with its preimage during the rotation

a. 2

b.4

c.6

d.8

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

36

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
