Answer: there is no answer involving real numbers
Step-by-step explanation:
Well, you need a diagram (see attached).
Since angle S = angle T then
9x -11 = 7x -3 ...... 2x = 8 ........ x = 4
RS = RT = 4
There must be some more information that can't be seen
14x + 70 + 20x + 8 = 180
34x + 78 = 180
34x = 102
x = 3
ABX = 14(3) + 70 = 112
CBX = 180 - 112 = 68
