HELP PLEASE Reflect ΔABC across the x-axis, and dilate it by a factor of 0.5 with respect to the origin to form ΔEFG.

Rotate ΔABC about the origin by an angle of 90° counterclockwise, and dilate it by a factor of 2.5 with respect to the origin to form ΔHIJ.

Record the areas of the transformed triangles. What is the ratio of the area of each transformed triangle to the area of ΔABC?

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

not sure but it may be b, as i said i'm not sure.
