4. Find the solution of the system y=- 2/5 x + 1
and 2x + 5y = 3 by any method. Classify the
system.

its kinda hard to answer this when we dont have all the information that we need.

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
