Question 964311
The shortest side would go opposite the smaller of the complimentary angles.


s+64+90=180
s=180-90-64
s=90-64
s=26  DEGREES


Make the drawing of this triangle and label everything.


LAW of SINES:

Using y for the longer side leg,


{{{7/sin(26)=y/sin(64)}}}


{{{y=7*sin(26)/sin(64)}}}


You should be able also to use Law of Sines to find the hypotenuse, or you could use Pythagorean Theorem formula with the y you found to solve for the hypotenuse.  You be able to figure out the rest of this.
