1. To which set or sets does the number 45/5 belong to? A. Integers only

B. Natural number only

C. Integer and rational number only

D. Natural number, whole number, integer, and rational number

you can't solve x because it is 2 linear equation and you only have one equation

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

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
