The polygons are similar, but not necessarily drawn to scale. Find the value of x.

Question

please show work
and answer quickly if you can

the first polygon the top is x-1 the right diagnal is y+1 the bottom is 32 and the left side is 16

the smaller one it the top is 6 diagnal is 21 bottom is 24 side is 12

Answer 1

since the corresponding sides are all in the same ratio,
(x-1)/6 = 4/3
so solve for x

Answer 2

Can you tell me where you got the 4/3 from?

Answer 3

X=9
