EASY I AM JUST DUMB HELP ASAP What is the value of x in the proportion r/h=h/x? A) r
B) a
C) b
D) s

There are 3 triangles in this diagram. Focus on the smallest triangle that is on the left side. This has a short leg of r and a long leg of h. Now move to the medium sized triangle on the right. It has a short leg of h and a long leg of s

we have these pairings

short legs = {r and h}

long legs = {h and s}

since we go from r to h, then h to s, we can say r/h = h/s
