Answer:
11 mm
Step-by-step explanation:
An octagon has 8 sides. This mean that we do 88 divided by 8 to get the length of each side which is 11 mm.
Answer:
61 and -87
Step-by-step explanation:
If the numbers are x and x - 148, we can write the following equation:
x + x - 148 = -26
2x - 148 = -26
2x = 122
x = 61 so x - 148 = 61 - 148 = -87

Rotation and reflection are instances of transformation

From the question, we have:


The rule of 90 degrees clockwise rotation is:

Using the above transformation, the new points would be



The next transformation is reflection over the x-axis
The rule of this transformation is:

So, the new points would be:
