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
