<PRE><B>Question 816615</B>
The exterior angles of a convex pentagon measure (18x+12), 16x, (8x+6), (10x-12), and (5x+12). Determine the measure of the largest interior angle.
-------
Equation::
18x+12 + 16x + 8x+6 + 10x-12 + 5x+12 = 360 degrees
-----------------------------------------------
57x + 18 = 360
-----
57x = 342
x = 6
------
18x+12 = 18*6+12 = 120
16x = 16*6 = 96
10x-12 = 60-12 = 48
8x+6 = 8*6+6 = 54
5x+12 = 5*6+12 = 42
------------------------
