Determine m < a, m < b, m < c
angle in triangle, and their sum is 180
so, if

m < a=+3x+%2B+5
m < b=+5x+-+18
m < c=7x+-+2
we have
+3x+%2B+5%2B5x+-+18%2B+7x+-+2=180
+15x-+15=180
+15x=180%2B15
+15x=195
+x=195%2F15
+x=13

m < a=+3x+%2B+5=3%2A13%2B5=44
m < b=+5x+-+18=5%2A13-18=47
m < c=7x+-+2=7%2A13-2=89

How can someone tell without any reference to where these angles lie? 

Plus, and FYI, angles are referenced by UPPER CASE letters, not lower case. Lower case letters are used to denote length of sides of polygons, as well as POINTS.
