Look at the figure shown below: which step should be used to prove that point j is equidistant from points k and m? a. in triangles jlk and jlm, all three angles are equal. b. in triangles jlk and jlm, one side and one common angle are equal. c. in triangles jlk and jlm, two sides and a common angle are equal. d. in triangles jlk and jlm, two angles and an included side are equal.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

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
