**Reiny**, Tuesday, January 10, 2012 at 1:12amlet the shorter side be a, then the longer side is a+x

by the Triangle Angle Bisector Theorm

(a+x)/5 = a/3

3a + 3x = 5a

3x = 2a

a = 3x/2 = 1.5x

so the sum of the three sides

= a + a+x + 8

= 1.5x + x + 8

= 2.5x + 8

**Anonymous**, Tuesday, January 10, 2012 at 9:31pmReiny, if a+a+x+8 then how come it is 1.5x+x+8=2.5x+8? I thought that it is 1.5x+1.5x+x+8=4x+8. Previous problem:one side of a triangle is x inches longer than another side. The ray bisecting the angle formed by these sides divides the opposite side into 3-inch and 5-inch segments. Find the perimeter of the triangle in terms of x.
