EASY I AM JUST DUMB!! WILL GIVE BRANLIEST!!! 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
The value of x is s , Option D is the correct answer.
The triangles that are similar in shape but the size might be different.
A triangle with two other triangles inside it is given.
Triangle arh and bsh are similar
as h is the common side
angle h is 90 degree
and r and s are in proportion
Therefore by property of similar triangles
r/h = h/s
and so
The value of x is s.
