Is there more context to the question?
Answer:
x = 4.5
Step-by-step explanation:
14 = 8/3x + 2
12 = 8/3x
36 = 8x
x = 4.5
Trigonometric Functions:


You have the angle and the adjacent. You need to find the hypotenuse (PR). Therefore, you use cos.

Rearrange the formula to find H (PR):

14.463 ~ 14.5
<h2>
14.5°</h2>
Remember that the formula for the circumference,
, of a circle is:

In this case, we are not given the diameter. However, remember that the diameter is equivalent to two times the radius of a circle. Thus,
,
and we can say the circumference of our circle is:

The circumference of our circle is 50.24 units.
<em>Also, a little side note not relating to the question:</em>
<em>Remember that
is spelled as "pi" not "pie." Pie is a dessert, while pi is a mathematical constant.</em>
