Find the measure of each angle in a triangle with angles: x, (x135), and 1/10 x

Geometry  Reiny, Sunday, September 30, 2012 at 8:34am
we know that
x + x135 + x/10 = 180
multiply each term by 10
10x + 10x + 1350 + x = 1800
21x = 450
x = 450/21 = 150/7
x = 150/7
x135 = a negative ! , OOPS, something is bogus about your data, an angle inside a triangle cannot be negative.
