Use the graph to answer the question.

Which series of transformations correctly maps parallelogram ABCD to parallelogram A′B′C′D′?

a 90∘ counterclockwise rotation about the origin, followed by a reflection in the y-axis

a 180∘ counterclockwise rotation about the origin, followed by a reflection in the y-axis

a 90∘ counterclockwise rotation about the origin, followed by a reflection in the x- axis

a 180∘ counterclockwise rotation about the origin, followed by a reflection in the x-axis

a 180∘ counterclockwise rotation about the origin, followed by a reflection in the y-axis

Step-by-step explanation: Mark me as brainliest

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
