Answer:
So,
if C = 2πR
you take 2π you get 6.28
so C=6.28 x r
the radius is 11.5 so
6.28 x 11.5 = 72.2566
the circumference is 72.2566
Step-by-step explanation:
It would be 32-4x=12
32-4(5)=12
32-20=12
12=12
ANSWER
The set of all rational numbers and the set of all real numbers.
EXPLANATION
The set of rational numbers contains all numbers that can be written in the form,

where a and b are integers and b≠0.
The given number is

It belongs to the set of rational numbers.
The set of rational numbers is a subset of the set of real numbers.
Hence

also belongs to the set of real numbers.
The correct answer is A.
Answer:
122°
Step-by-step explanation:
The formula for finding the sum of all angles in a polygon is:
(n-2) * 180°
n is the number of angles
Here n = 7, so the sum of all angles is
(7-2) * 180° = 900°
x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°
Make me the brainliest ;)
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
