Find the value of 'x' and state which angle on triangle ABC is smallest. A = right angle, B = 2x + 30, C = 2x

Where the angles of a triangle A+B+C = 180 degrees, then if follows that (where A = 90, B = 2x + 30, C = 2x):180 = 90 + 2x + 30 + 2x180 = 120 + 4x60 = 4x15 = xTherefore, it follows that A = 90, B = 60, C = 1...
