Answer:
The perimeter is 70
Step-by-step explanation:
Isosceles means all sides same length. So to start out, you need to firgure out x so you can do let's say 3x-5=19x, or you can do 2x=19-x, or an combination pretty much. Once completing this, you find that x=14. Now all you have to do is plug 14 into all the x spots, and add everything together
