Answer:
A. x-6
Step-by-step explanation:
The area of a square is given by the expression square inches. Now we need to find an expression that represents the length of one side of the square, in inches. To do that we need to factor
.
Since area of square is given by (side)^2
Hence one side of square is (x-6).
So choice A. x-6 is correct.
Given:
In triangle DEF, HG is parallel to DF.
To find:
The value of x.
Solution:
In triangles DEF and GEH,
(Common angle)
(Corresponding angle)
(By AA property of similarity)
We know that corresponding sides of similar triangle are proportional.
Isolating variable terms, we get
Therefore, the value of x is equal to 4.
