The perimeter of a scalene triangle is 14.5 cm. the longest side is twice that of the shortest side. which equation can be used to find the side lengths if the longest side measures 6.2 cm?

Perimeter of scalene triangle = a+b+c (where they are sides)

c=6.2 (given)

a=3.1

so, 14.5 = 3.1+b+6.2

b=5.2

In that way, sides will be 3.1cm, 5.2cm & 6.2cm

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
