Segment ab is on the line y − 9 = −4(x + 1), and segment cd is on the line y − 6 = one fourth(x − 3). which statement proves the relationship of segments ab and cd?
a. they are perpendicular because they have slopes that are opposite reciprocals of 4 and negative one fourth.
b. they are parallel because they have the same slope of 4.
c. they are perpendicular because they have slopes that are opposite reciprocals of −4 and one fourth.
d. they are parallel because they have the same slope of negative one fourth.

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
