Question

A triangle has a perimeter of 3063 mi. The short side measures 79 mi less than the middle side, and the long side measures 376 mi more than the middle side. Find the lengths of the three sides.

Answer 1

x+y+z = 3063
y-79=x
z-376=y
z-455=x
z + (z-455)+ z-376 = 3063
3z-831= 3063
z = 1289
y = 913
x= 834
