Could I Get My Away 'Carry-On' and Beis 'The Backpack' Fit in RyanAir?

I've purchased the "priority" pricing for a few RyanAir flights and was wondering if my Beis 'The Backpack' can be considered a personal item and if my Away 'Carry-On' will be able to pass for my 10kg bag?
The measurements of the Away 'Carry-On' is 55.1x36.5x24.4cm
RyanAir's measurements are 55x40x20cm
For the personal item, which would be the backpack, it measures 33x48x13.9cm
RyanAir's measurements are 40x20x25cm
I was wondering if I would be able to get away with this, as some measurements are less than the requirements but some go over...
