Point s is between r and t on segment rt . use the given information to write on equation in terms of x. solve the equation. then find rs and st. rs = 2x + 10 st = x - 4 rt = 21 rs = st =

Respuesta :

RS + ST = RT
The equation is:
2 x + 10 + x - 4 = 21
3 x + 6 = 21
3 x = 21 - 6
3 x = 15
x = 15 : 3
x = 5
RS = 2 * 5 + 10 = 10 + 10 = 20
ST = 5 - 4 = 1
Answer: Segment RS = 20 and ST = 1
