Answer: y-axis

Step-by-step explanation:

The equation of the line of reflection is the perpendicular bisector of the segment that connects a point on the preimage and the corresponding point on the image.

For this, we'll consider A(-1, -1) and A'(1, -1).

The equation of this line is clearly y = -1, and its midpoint is (0, -1).

This means the line of reflection will be a vertical line passing through (0, -1), which is the line x = 0, or the y-axis

Answer:

12

Step-by-step explanation:

This thing to know about this question is that angle 1 and angle 3 are actually the same.

When two lines intersect, the opposite angles such as that shown in 1 and 3 are equal to each other.

So what you can do is set angle 1 and 3 equal to each other like so:

5x+10 = 70

Then solve for x

5x+10 = 70

5x = 60

x = 12
