AC≅CE and D is the midpoint of CE. If CE = 10x+18, DE = 7x–1, and BC = 9x – 2, find AB. *

the answer is 15% decrease

answer: (3,11) is your answer.

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
