Triangle ABC is placed on a coordinate grid at the origin. The triangle is translated 4 units left, then 2 units up. Finally, it is reflected across the y-axis to display triangle A'B'C

so what is the question

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

i belive those are the ones that are under 90 degreese.

your answer is the frist one

hop i
