Draw a line from point Q to point A. Then draw another line segment from point Q to point A'. These lines are marked in red in the attached image (figure 1). Notice we have a 90 degree angle form. To go from A to A', we rotate 90 degrees counterclockwise (green angle in figure 2). Or we can rotate 270 degrees clockwise (gray angle in figure 2).
So that's why the two answers are:
choice B) 90 degrees counterclockwise
choice D) 270 degress clockwise
Side Note: the other points (B, C, and D) will follow a similar rotation path compared to point A. Either rotate those preimage points 90 degrees counterclockwise or 270 degrees clockwise so they match with their respective image points. All rotations are done around point Q.
Answer:
D is the answer since you added all the numbers together ten divide by five
Answer:
an = 56-8(n-1)
Step-by-step explanation:
This is an arithmetic sequence
The common difference is 48 - 56 =-8
a1 = 56
an = a1+d(n-1)
an = 56-8(n-1)

Answer:
3sqrt(2)
Step-by-step explanation:
The upper triangle is a 30-60-90 triangle. The hypotenuse is twice the length of the small leg.
30-60-90 triangle
hypotenuse = 6
small leg = 3
The small leg of the 30-60-90 triangle is the leg of the lower triangle.
The lower triangle is a 45-45-90 triangle. The hypotenuse is sqrt(2) times the length of the leg.
45-45-90 triangle
leg = 3
hypotenuse = 3sqrt(2)
x is the hypotenuse of the 45-45-90 triangle.
x = 3sqrt(2)
