I don't know how to explain this but I'll try.

The sides of a triangle are 4 ft (left side), 6.4 ft (right side) and 5.6 ft (bottom). And then on the inside the angles are 82, 60, and 38. The question asks what is wrong with the "labels" on the kitchen triangle (because the problem is a "kitchen triangle" located in where else but a kitchen.... dur.)

I could be wrong, but I think the answer is the triangle is wrong because perimiter of a triangle is supposed to add up to 180 but in this problem it adds up to 160. Am I right? Someone please help me!

The angles have to add up to 180 degrees.
There is no theoretical limit to the perimeter of a triangle.

An illustration showing the labels would help. But here's something you can investigate.
if A, B and C are the sides of a triangle, and a, b and c are the angles opposite each of those sides respectively, then

sin(a)/A = sin(b)/B = sin(c)/C (The law of sines)

Work through the numbers. If the numbers and labels are correct, these equalities will check out.

Some figures to help
sin(82 degrees) = .9903
sin(60) = .8660
sin(38) = .6157

No, I believe only the angles need to add up to 180 degrees

yea i think its the 160 because to be a straight line like all angles add up to be is 180 and if its not its wrong
