Answer:

Step-by-step explanation:
If the figures are similar, then the angles are the same. So that means that angle H is equal to angle D (you can count he little arcs in the angle to find it's matching partner). Since this is true:

Which is the same as
. Solve for x by dividing both sides by 4:

Finito.
Hello,
Let's z=0.1234567891011121314151617181920.....(never end)
2/5=(2/(5z)*z<3241/1000 *z
3/4=(3/(4z))*z>6075/1000*z
So here is 2836 irrational numbers:
3241*z/1000
3242*z/1000
3243*z/1000
...
6073*z/1000
6074*z/1000
6075*z/1000
