Answer:

36

Step-by-step explanation:

We know the legs of an isosceles triangle are equal.

Therefore 3x-1 = -x+27

We can add x to both sides to get 4x-1=27

Add 1 to both sides to get 4x=28

Divide each side by 4 to get x=7

We can plug x into the base equation 5x+1

5(7)+1 = 35+1 = 36

The base length is 36

Answer:

Step-by-step explanation:

As it is an isosceles triangle, 3x - 1 = -x + 27

3x - 1 = -x + 27

3x + x = 27 +1

     4x = 28

       x = 28/4

      x = 7 units

Length of the base = 5x + 1 = 5*7 + 1 = 35 +1 = 36 units
