Hi

I think the correct answer in test n. 4 in "The Angles of a Triangle " in "Scientific Expedition" must be

[90,53,37],

in attached screenshot you can see that you answer is

"Right result: [37,53,90]"

but for "checkio(5,4,3)" on first place must me 90, because '5' on first place and the biggest angle must be vis-a-vis with it

p.s. in task you have this line: assert checkio(3, 4, 5) == [37, 53, 90], "Egyptian triangle" and this result as the same for checkio(5, 4, 3) in test n.4

Best wishes
