I have a triangle one side = 3
side 2 = square root5 - square root 3
side 3 = square root 5 + square root 3
I can get the answer 3 and I know I am missing the square root part of the equation can you help me by showing how this problem is worked so I can see where I am missing it?

What are you trying to solve?

the perimeter,
ã5 - ã(3 ) side 1
ã5 + ã(3 ) side 2
4 side 3
It looks like the side 1 and 2 cancel out each other just leaving side 3 with is 4. Is this correct?
