im pretty sure this is the answer
We know that 1 side is 100 and 1 angle is 90 degrees
we would need at least 1 more angle or 1 more side length to say that they are similar
no
but, if we asssume that DCB is a straignt line, then we can say that they are similar
2. if we say taht they are similar then DE=AB, so then 175=DE=AB
The given equation is

hence

But x cannot be zero so x=3
So the value of x is 3
