ALGEBRA Find x and y so that each quadrilateral is a parallelogram. (Please do at least 2, but doing all 4 would be greatly appreciated, and i will mark u brainliest.)

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

16 is the coefficient

hope this
