Given that △DEF is congruent to △D′E′F′. A student incorrectly described the sequence of transformations that maps △DEF onto △D′E′F′ as a reflection across the x-axis, followed by a translation 6 units right and 4 units up.

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
