Answer: The value of x =2 units.
Explanation:
Since we have given that
AD= CD
BE= EA
So, we get that D and E are the mid-points of AC and AB respectively.
So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

So, we put the value of DE and BC ,

Hence, the value of x =2 units.
Assuming you meant square root of 90 it would be
90 equals 3 times the square root of 10
√90 = 3√10
Is there any choices if not it could be 1 - 2 or abouve the first nuber x has to be smaller and y has to be bigger
For this case we have the following equation:

Resolving we have:

We apply distributive property to the terms of parentheses:

Adding 6 to both sides of the equation:

Dividing between 3 on both sides of the equation:

ANswer:

1/15. 8/60 simplified down is 1/15
