Identify the conditionals and truth values implied by the following biconditional. Select all that apply. Two lines are parallel if and only if they do not intersect.
A. If two lines are parallel, then they do not intersect; T.
B. If two lines are not parallel, then they intersect; F.
C. If two lines do not intersect, then they are parallel; T.
D. If two lines do not intersect, then they are parallel; F.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

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
