If this trapezoid is moved through the translation (x+3,y-2),what will the coordinates of A’ be

9514 1404 393

  A'(-3, 0)

Step-by-step explanation:

The coordinates of A are (-6, 2). Use these (x, y) values in the translation expression to find the coordinates of A'.

  (x, y) ⇒ (x +3, y -2)

  (-6, 2) ⇒ (-6 +3, 2 -2) = (-3, 0)

The coordinates of A' are (-3, 0).

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
