The nth term of a sequence is 2n + 1 The nth term of a different sequence is 3n - 1

Work out the three numbers that are in both sequences and also between 20 and 40

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

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

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
