Problema Solution
A certain triangle has a perimeter of 3078 mi. The shortest side measures 79 mi less than the middle side, and the longest side measures 373 mi more than the middle side. Find the lengths of the three sides.
Answer provided by our tutors
let 'x' represent the middle side, then 'x-79' represents the shortest side and 'x+373' represents the longest side
3078 = x + x-79 + x+373
solving for 'x' we have x=928
928-79 = 849
928+373 = 1301
the three sides are 849 mi, 928 mi, and 1301 mi
