A (2,3)

B (3,2)

D (3,4)

F (3,-2)

A' (3, 2 )

Step-by-step explanation:

x = 3 is a vertical line passing through all points with an x- coordinate of 3

A ( 3, 2 ) has an x- coordinate of 3 meaning it lies on the line x = 3

Thus this point will remain unchanged under a reflection in the line x = 3 , so

A' = (3, 2 )

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
