Given the vector u equal to 3 (cos 280º, sin 280°) and vector v equal to 5 (cos 215°, sin 215°), find the sum u + v and write your answer in magnitude

and direction form with the magnitude rounded to the nearest tenth and the

direction rounded to the nearest degree, 0º = 0 < 360°.

b if for most of the graph

d if y intercept

step-by-step explanation:

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
