Question

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

Answer 1

B

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=(30)/(6)\\x=5`

x is 5, so B is the correct answer.
