Reflecting over the x axis means to perform the following tranformation:

So, you maintain the x coordinate, and change the sign of the y coordinate. The vertices become

Translating 3 units to the left means to perform the following transformation:

So, you maintain the y coordinate, and decrease the x coordinate by 3. The vertices become

So, as you can see, after these two transformation, the vertices A, B and C become A', B' and C'.
Answer is $114.75. This is found by taking 1.35% of 8,500.
Answer:
A(-2,0) B(-4,0) C(-5,2) D(-1,2)
Step-by-step explanation:
To answer this question, you can use the values of the unit circle to figure out the angle measurement. Since the cosine is the x value of the circle, we can see that at 45°<span>, the x value is √2/2.
So the missing angle should be 45°</span>
