Question 611355
<font face="Times New Roman" size="+2">


Since both of the given conditions are referenced to the second angle, let *[tex \Large x] represent the measure of the second angle.  Then the measure of the first angle is *[tex \Large x\ +\ 12] and the measure of the third is *[tex \Large 2x\ -\ 4]


Add the three expressions for the three angles and set them equal to the number of degrees that represents the sum of the measures of the angles in all triangles.


Solve for *[tex \Large x] then calculate *[tex \Large x\ +\ 12] and *[tex \Large 2x\ -\ 4]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
