I think that in the last test №4 wrong answer

import math

def checkio(a, b, c):

    #replace this for solution
    if (a + b) > c and (b + c) > a and (a + c) > b:
        A = round(math.degrees(math.acos(((b ** 2 + c ** 2 - a ** 2)/(2 * b * c)))))
        B = round(math.degrees(math.acos(((a ** 2 + c ** 2 - b ** 2)/(2 * a * c)))))
        C = 180 - (A + B)
        lst = []
        lst.append(A)
        lst.append(B)
        lst.append(C)
        print(A,B,C)#[A,C, B]
        return lst 
    else:
        return [0, 0, 0]
