Question

The measure,in degrees,of the three angles of a triangle are given by 2x + 1,3x - 3, and 9x.Whar is the measure of the smallest angle

Answer 1

(2x+1)+(3x-3)+9x = 180

14x-2 = 180

14x = 182

x = 13


Plugging back in, your angles are 27 degrees, 36 degrees, and 117 degrees, respectively.  So the 2x+1 angle is the smallest.
