In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.
The number of independent ways by which a dynamic system can move, without violating any constraint imposed on it, is called number of degrees of freedom.
In other words, the number of degrees of freedom can be defined as the
minimum number of independent coordinates that can specify the position
of the system completely.

The degree of freedom represents the number of ways in which the expected classes are free to vary in the chi-square goodness-of-fit test.</span>
The greatest common factor is 4

because that's where the lines intersect
Answer:

Step-by-step explanation:
we are given opposite and adjacent
we want to figure out x°
remember that,

where our opp is 5 and adj is 12.5
let
be x°
so


by using calculator

hence,
our answer is a
A/b+c/b=(a+c)/b
make bottom number same
multiply by 1 or x/x where x=x
easy way is
if you had
a/b+c/d
multiply a/b by d/d and multiply c/d by b/b
2/5 times 4/4=8/20
2/4 times 5/5=10/20
add
8/20+10/20=(8+10)/20)=18/20=9/10
I should have simplified 2/4 to 1/2 first
