Question 515114
Suppose a triangle has angles defined by the following expressions: angle A = 3x + 27; angle B = 5x - 13; and angle C = 4x + 24. 
----------------
A + B + C = 180 degrees
3x+27 + 5x-13 + 4x+24 = 180
12x + 38 = 180
12x = 142
x = 11 5/6
----
B = 5x-13 = 5(11 5/6) -13 = 46.1667 degrees
