Answer:

20 units

Step-by-step explanation:

Let the equal sides of the triangle be x.

Then the third side will be (x+5) units

Since the perimeter is 50, we have:

[tex]x + x + (x + 5) = 50[/tex]

We simplify to get:

[tex]3x + 5 = 50[/tex]

This implies that:

[tex]3x = 50 - 5[/tex]

[tex]3x = 45[/tex]

Divide both sides by 3 to get:

[tex]x = \frac{45}{3} = 15 [/tex]

The length of the third side is:

15+5=20
