Answer:

Step-by-step explanation:
Given the rhombus CDEF, sides FC and CD are adjacent sides.
Using coordinate geometry, to proof that a quadrilateral is a square, with regards to the slope, the slope of adjacent segments must be negative reciprocals.
In fact, by definition: Two lines with slopes
are perpendicular if:

Therefore if :
- FC and CD are adjacent segments
- Slope of FC=25
For the rhombus to be a square:
Slope of CD 
You divide 166 by 2. The answer would be 83.
No it's 3, it's sort of like the saying 3 strikes you're out basically after the third time you mess up there is no going back.
