Answer:
in order: 60, 60, 120, 120 (all of them in degrees)
Explanation:
We need to add all four angles given (I'll use 0.5 instead of 1/2 to make the addition easier to type):
0.5 x + 0.5 x + x + x = 360
3 x = 360
x = 360/3 = 120
Therefore,
now the angles are:
two of them are 1/2 of x, that is: 120/2 = 60
Then smallest angles are:
the largest are directly equal to "x", that is:
