Answer:
radius =1.1618m
Step-by-step explanation:
circumference of circle =7.3m
2πr=7.3
r=7.3/(2π)=1.1618m
Answer:
L = 2r + 3
Step-by-step explanation:
Given parameters:
Area of rectangle = 14r + 21
Width of the rectangle = 7ft
Unknown:
Length of the rectangle = ?
Solution:
If the length of the rectangle is designated as L;
Area of a rectangle = Length x width
Now insert the parameters:
14r + 21 = L x 7
L =
L = 2r + 3
Theorem
In a triangle, the measure of an exterior angle equals the sum of the measures of its two remote interior angles.
x + y = z
4n - 18 + n + 8 = 133 - 6n
5n - 10 = 133 - 6n
11n = 143
n = 13
z = 133 - 6n = 133 - 6(13) = 133 - 78 = 55
Answer: C. 55
The answer is 18 beacause 6+6+2+4=18
Answer:

Step-by-step explanation:
For
, there are two possible cases:

Solving for both cases, we get:
