So to rewrite it so that we can find the side, we just need to isolate the a variable.

So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be 
Im not entirely sure but, if you're on plato answer D is correct
model 1 has a random pattern and is fit for the data

Answer:
Measure of ∠FGE is 40.2°.
Step-by-step explanation:
Refer to the attachment.
Consider ΔFGE. Given that ∠FEG = 90° and ∠FGE is x°.
To find the value of ∠FGE use trigonometric ratios.
Use sine ratio to find the value of ∠FGE.

Rewriting it in terms of x° as follows,

Now find the opposite and hypotenuse side of the angle ∠FGE.
So opposite side of ∠FGE is FE and hypotenuse side of ∠FGE is FG.
Substituting the values,

Given that length of FE is 12 inch and FG is 18.6 inch.
Substituting the value,

To find the value of x, taking inverse sin.

Calculating the value,

Rounding to nearest tenth the value of angle is 40.2
Therefore measure of ∠FGE is 40.2° .
I believe it’s C 5(x+2-3) sorry if i’m wrong
