The answer is Letter B - x = 1.5.
First, we'll get the length of the "point" where the circle and the line meets to "S". Since RS = 11, we'll subtract x from 11. So its measurement is 11 - x and that is equal to "S" to the "point". After, we'll get "point" to "T". ST = 14, we'll subtract 11 - x from 14. We can get 4 + x. That measurement is equal to T to "point". The repeat the same process until you reach "point" to R, 3 - x.
To get x, equate both equations. Transpose and simplify.
x = 3 - x
2x = 3
x = 1.5
