Answer:

  A: ∠W'Z'Y' = 60°; angles aren't changed by rotation

  B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)

Step-by-step explanation:

<u>Part A</u>:

Angle WZY is the supplement of the given angle ZWX, so is ...

  ∠WZY = 180° -120° = 60°

Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...

  ∠W'Z'Y' = 60°

__

<u>Part B</u>:

The transformation right 2 and up 3 can be described by ...

  (x, y) ⇒ (x +2, y +3)

Then the translated vertices are ...

  W(-5, 3) ⇒ W'(-3, 6)

  X(7, 3) ⇒ X'(9, 6)

  Y(6, -2) ⇒ Y'(8, 1)

  Z(-6, -2) ⇒ Z'(-4, 1)

If m RDC = 120°, then m DAC=?
monitta
The correct answer to this question is 240

From the image i've seen, the RDC has an angle of 120. So the major arc DC (that passes A and B) has an angle of 240.

So this makes that the measure of the angle of DAC is 240 because of the angle formed by RDC which is 120.
