nurali · Answer

x = base 
2x = each of the congruent sides. 
Add all the sides up to equal 120. 
x + 2x + 2x = 120 
Simplify. 
5x = 120 
x = 24 
Base would = 24 inches.

These questions are about middle school level. If you are holding up in middle school by doing this. You will definitely fail in high school. I suggest you pay attention in class or get some extra help from your teachers so you can do these questions on your own.
