Answer:
Only a scalene triangle would have the given side lengths making it a unique triangle.
Step-by-step explanation:
To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is

.
Let's perform step 1: reducing one side to variables only. By adding

to both sides of the equation, we get

.
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of

is

, we need to divide both sides of the equation by 4:

. Rounded to the nearest tenth,

.
So the value of

that satisfies

is

.
Answer:
B
