Your calculator says error because you cant have a square root of a negative number because there is no solution to that maybe recheck your equation and try again

Find x A)-2 B)5 C)-5 D)9

Arte-miy333 [17]

Answer:

Step-by-step explanation:

From the figure, we can say:

∠NFG + ∠EFN = ∠EFG

We substitute the given measure and write:

6x + 4 + 24 = 12x - 2

Now, we simply solve this algebraically for "x". Shown below:

$6x + 4 + 24 = 12x - 2\\6x+28=12x-2\\28+2=12x-6x\\30=6x\\x=\frac{30}{6}\\x=5$

x is 5, so B is the correct answer.
