Answer:
RS: 26
ST: 40
Step-by-step explanation:
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 + 24 = 60 + 24
7x = 84
7x / 7 = 84 / 7
x = 12
---------------------------------------
RS
3x - 16
3 (12) - 16
36 - 16
20
---------------------------------------
ST
4x - 8
4 (12) - 8
48 - 8
40
----------------------------------------
RS + ST = RT
20 + 40 = RT
60 = RT
