The value of x in the triangle is 9.3
<h3>How to find the side x of a triangle?</h3>
The side x of a triangle can be found as follows:
The triangle ABC is similar to triangle ADE.
Therefore, corresponding sides of similar triangles are in the same ratios.
Hence,
7 / 13 = x / x + 8
cross multiply
7(x + 8) = 13x
7x + 56 = 13x
subtract 7x from both sides of the equation
7x - 7x + 56 = 13x - 7x
56 = 6x
divide both sides by 6
x = 56 / 6
x = 9.33333333333
x = 9.3

Answer:
QS = 38
Step-by-step explanation:
First, we need to find the value of x.
Given that R is the midpoint of Q and S, that means QR = RS.
6x-11 = 2x+9
Solve.
x = 5.
To find QS, we need to solve the following equation:
6x-11 + 2x+9
Substitute 5 for x.
6(5)-11+2(5)+9
30-11+10+9
38
