Answer:
x is 18 degrees
Step-by-step explanation:
We know that any straight line is 180 degrees. If you didn't know that:
A circle is 360 degrees and if you put a line through the middle, you would have 180 degrees on both sides.
Now, the angles are 4x and 6x and we want to solve for x, we can create the equation:
4x + 6x = 180 degrees.
We can add the x's together to get:
10x = 180
We can then divide both sides by 10 to get:
/10 /10
<em>x = 18 degrees</em>
it is D.4
each place on the number line goes up by 4
