a = longest
b = middle
c = shortest
================================
a = 2x
b = x + 14
c = x
================================
2x + x + 14 + x = 180
4x + 14 = 180
4x - 166
x = 41.5 degrees.
===============================
a = 83 Degrees
b = 55.5 Degrees
c = 41.5 Degrees
===================================
83 degrees + 55.5 degrees + 41.5 degrees
This does check.
