What is mzyxs?
the image of trapezoid pqrs after a reflection across line wy
is trapezoid p'q'r's'.
45°
90°
180°
270°

The angle YXS is 90°, because the line WY is perpendicular to segment SS'. This is graphically seen, because WY is vertical and SS' is horizontal. So, we know that the angle between a horizontal and vertical line is always perpendicular, that is, 90°.

Therefore, the second option is correct.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
