The sum of the angle measures of any trapezoid is greater than the sum of the angle measures of any parallelogram is it true or false and explain how

False

Step-by-step explanation:

It is known that the trapezoid and a parallelogram both are known as quadrilaterals and has four sides and four angles.

Also, we know that  the sum of the angles of both the trapezoid and the parallelogram is 360°, therefore the given statement that is The sum of the angle measures of any trapezoid is greater than the sum of the angle measures of any parallelogram is False as the sum of both trapezoid and the parallelogram are equal.

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
