Erika cuts out a paper quadrilateral with two angles that each measure 60 degrees and two angles that each measure 120 degrees. Only two of the sides have a length of 3.2 inches. Select all the possible quadrilaterals that Erika could have made. A. Parallelogram
B. Rectangle
C. Rhombus
D. Square
E. Trapezoid

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

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
