C. 5

Step-by-step explanation:

Midsegment is the half of the sum of the bases:

EF = 1/2(AB + DC)8.8 = 1/2(12.6 + x)12.6 + x = 2*8.8x = 17.6 - 12.6x = 5

Correct option is C

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
