5x^2-45=0

<em>*Add 45 to both sides*</em>

5x^2=45

<em>*Divide both sides by 5*</em>

x^2=9

<em>*Take the square root of both sides*</em>

x=+/-9

Answer:

A. 8

Step-by-step explanation:

The angle shown is a 90 degree right angle (shown by the box where the vertex is)

We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.

5x=40

After dividing both sides by 5, we get x = 8
