Is 17x-2 supposed to be angle T? This is a bad question; demand better from your teachers.
Let's assume 17x-2 = angle T. S is a right angle because it's subtended by a diameter, Thales' Theorem. R is half 116 degrees, so 58 degrees. T is complementary, T=90-58=32 degrees.
17x -2 = 32
17x = 34
x = 2
Answer: 2
