∆ABC is reflected across the y-axis and translated 3 units up to create ∆XYZ. Select all statements that are true about ∆ABC and ∆XYZ.

Step-by-step explanation:

Suppose A is (-3,6) when it starts out.

Now we take the reflected point and move it three units. up

∆ABC  is congruent to ∆XYZ.

Corresponding sides of  ∆ABC and  ∆XYZ  are not congruent.

Corresponding angles of  ∆ABC and  ∆XYZ  are congruent.

Step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

this is answer of 144 cubic meters
