<PRE><B>Question 493677</B>
A = x
B = 2x - 12
C = 2x
================================
x + 2x + 12 + 2x = 180
5x - 12 = 180
5x = 192
x = 38.4 degrees
==================================
A = 38.4 degrees
B = 64.8 degrees
C = 76.8 degrees.
==================================
38.4 + 64.8 + 76.8 = 180 degrees
This does check.
