Polygon FGHIJ is the result of the rotation of ABCDE.
A = F ⇒ 117°
B = G ⇒ 90°
C = H ⇒ 127°
D = I ⇒ 90°
E = J ⇒ 117°
The measure of angle BCD remains the same because the rotation involves the whole polygon. Thus, it is still 127°

Answer:
Reflection over the x-axis
Step-by-step explanation:
Process of elimination, all of the other answers and the image is reflected over the x-axis perfect.
If rotated 270 degrees the image would be vertical
If reflected over the y-axis the image would be in Quadrant I not II
If rotated 90 degrees the image would be vertical as well.
So all othe the other answers are wrong making B) right.
Answer:
26/32=13/16
Step-by-step explanation:
Answer: The required number of boys in the class is 18.
Step-by-step explanation: Given that in math class, the girl to boy ratio is 8 to 6 and there are 24 girls in the class.
We are to find the number of boys in the class.
Let 8x and 6x represents the number of girls and boys in the class.
Then, according to the given information, we have
Therefore, the number of boys in the class is given by
Thus, the required number of boys in the class is 18.
Y = |x| translated 1 unit left and 2 units up gives the equation
y = |x + 1| + 2
