<PRE><B>Question 1097155</B>
The sum of the exterior angles = 360
Let A = the smallest exterior angle
Then the other two angles are 5/4A and 6/4A
Find A:
A + 5/4A + 6/4A = 360
15/4A = 360
A = 96
The interior angles are, therefore, 180 - 96, 180 - (5/4)96, and 180 - (6/4)96
Interior angles: a = 84, b = 60, c = 36
So the ratio of the triangle is 60/84 = 5/7, 60/36 = 5/3, or 3:5:7</PRE>
