Answer:
Step-by-step explanation:
Suppose we have a triangle WXY whose internal angles are:
The sum of the measures of the angles must be 180°, thus:
Simplifying:
15x + 15 = 180
Subtracting 15:
15x = 165
Dividing by 15:
x = 11
Thus, the measure of angle Y is
Rotation and reflection are instances of transformation
See attachment for the new position of
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:
See attachment for the new points
