Answers
Answer:
x = 37
Step-by-step explanation:
The angle with a measure of 74 degrees and the angle labeled "2x" are vertical angles
Vertical angles are congruent ( equal to each other )
Hence, 74 = 2x
^(note that we just created an equation that we can use to solve for x)
Now we solve for x
74 = 2x
step 1 divide each side by 2
74 / 2= 37
2x / 2 = x
we're left with x = 37

Find the circumference of the circle. Use 3.14 for pi
Answers
Answer:
A. C = 43.96
Step-by-step explanation:
Circumference = Diameter * pi
Your diameter in this problem (given by the picture) = 14 inches.
If we plug this into the formula:
C = 14 * 3.14 = 43.96
There is a problem with your question, however, because the length we have found is in inches, while all of your options are in centimeters. However, converting the correct inches answers into centimeters is not an answer choice.
pi = 3.14
diameter = 14 in
3.14 x 14 = 43.96 (option 1)
