Can somebody me with questions 27 and 28?

check the picture below.

27)

since those angles on the other side, are alternate interior angles, then ∡RST = 110°.

28)

for the same reason, those angles on the outside are alternate interior angles to 110° and 120°, and those angles outside are linear angles with the ones inside, recall linear angles add up to 180°.

therefore ∡RST = 130°.

Cis your correct answer

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
