Two angles are 90.
The remaining angles sum to 70.
That makes the sum of the interior angles,
90%2B90%2B70=250
The formula for the sum of the interior angles based on the number of sides is,
%28n-2%29180=250
n-2=25%2F18
Not an integer solution so those angles cannot be the sum of interior angles of any polygon.
