Well,

I assumed that the total current should be around 100mA.

Both resistors in series conduct the total current.

100mA on a 109 ohm creates 1.1W dissip; and the 19 Ohm is roughly 1/5th of it which is 0.2W.
I use a factor of 5x to size up resistors. So it becomes 5W and 1W.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
