Question 423894
Let x = smallest angle
Then the 2nd angle = x + 13
The 3rd angle = 2x  + 15
And the 4th angle = x + 27
We know the sum of the 4 angles is 360 degrees:
x + x + 13 + 2x + 15 + x + 27 = 360
Collecting terms gives 5x = 360 - 55 -> x = 61 deg.
So the 2nd angle = 61 + 13 = 74 deg.
The 3rd angle = 122 + 15 = 137 deg.
And the 4th angle = 61 + 27 = 88 deg.
Ans: 61, 74, 88, 137
