If Triangle ABC is dilated using a scale factor of 5 to produce Triangle XYZ, what do you know did not change in the dilation?

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
