Using proportions, it is found that the value of a is of 3.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, a 180º angle has a measure of 
radians. What is the measure of a 540º angle? The <em>rule of three</em> is given by:
180º - rad.
540º - x rad.
Applying cross multiplication:
180x = 540.
x = 540/180 = 3.
The value of a is of 3.

Answer:
D
Step-by-step explanation:
first distribute 6 to get
(18x - 8) +44
combine like terms
18x + 36
You simply divide, since it's a fraction. If you divide 14 b7 25, you get an answer of 0.56. :)
The equation of a circle with center (h, k) and radius r is
In this case, the center of the circle is (-3, 2), and the radius is 3.
You have h = -3, k = 2, r = 3
Simplifying, you get
