<PRE><B>Question 546256</B>
The sum of the angles of a triangle is 180 degrees.

angle 1 = x

angle 2 = 3x/4

angle 3 = (2/3)(3x/4)

 
x + 3x/4 + (2/3)(3x/4) = 180


After doing the math, I found angle 1 = 80 degrees, angle 2 = 60 degrees and angle 3 = 40 degrees.  


The prove:

The sum of the angles of a triangle is 180 degrees.


80 + 60 + 40 = 180


180 = 180...It checks!!
