Answer:
x = 8 units
Step-by-step explanation:
Note that the ratio of the middle-length legs is 12/18, and that of the shortest-length legs is x/12.
Then:
12 x
----- = -----
18 12
... which, through cross- multiplication, becomes 18x = 144. Then x = 8 units

Because thee dimensions of ΔRAH is twice as large as corresponding dimensions of ΔEAC,
|RA|=2|EA|=2*3.5=7
|AH|=2|AC|=2*6=12
So, we have that 2 corresponding sides are in proportion and angle between them =90⁰, so the angle between them are congruent,
we can use SAS to prove that these triangles are similar.
