Question 814124
Imagine the 2.5 inch side with a cut {{{90-32=58}}} degree cut, such that this cut starts from a corner where the 14 inch side and 2.5 inch side meet, and ends through a point on the 14 inch side.  DRAW this.


{{{highlight(y/2.5=tan(58))}}}
If this equation makes sense to you, then you're all set.
y is the point along the 14 inch side where the cut would be finished.
