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.

x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
Answer:
4.
Step-by-step explanation:
He starts off by distributing the 5 to the x and to the other 5.
