We know that we can use trigonometry to solve for x here.

If we use tangent, we can solve for x directly:

tan(theta)=\frac{opposite}{adjacent}

tan(60)=\frac{x}{6}

6*tan(60)=x

x=6\sqrt{3}

So therefore we have solve for x, which is D) 6\sqrt{3}.

Lera25 [3.4K]

Answer:

2i or -2i

Step-by-step explanation:

2x² = -8     First, clear x.

x² = -8/2    Solve

x² = -4        Now, eliminate the square of x by solving the square root of -4.

x = √-4

x = 2i or -2i Is an imaginary number.
