Which rule yields the dilation of the figure qrst centered at the origin? a) (x, y) → (3x, 3y) b) (x, y) → ( 1 3 x, 1 3 y) c) (x, y) → (x + 3, y + 3) d) (x, y) → (x + 1 3 , y + 1 3 )

18.8cm hope i at all

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
