Answer:

  • x = 11
  • midline = 16
  • baseline = 32

Explanation:

You have a triangle with its midline length given as x+5 and its parallel base line length given as 3x-1. We presume you want to know the value of x and the lengths of the segments.

Midline

The midline is half the length of the parallel base line, so you have ...

x +5 = 1/2(3x -1)

Solution

2x +10 = 3x -1 . . . . . . . multiply by 2

11 = x . . . . . . . . . . . . . add 1-2x

The midline length is x+5 = 11+5 = 16.

The base line length is 3x-1 = 33 -1 = 32, twice the length of the midline.

The solution to the triangle is ...

  • x = 11
  • midline = 16
  • base line = 32
