Answer:
20-20-20(20 on each side)
Step-by-step explanation:
Okay, so what it's asking is to find 'x' and plug it in to find the missing sides. But, they all are equal to one another.
So the equation could be something like this:
4x=3x+5(Just to find x)
-3x -3x
Then you'd have x=5
You'd plug it in and you'd have your answer of 20 for each side
