That looks like a neat calculator. And fully able to calculate any right triangle from two knowns (at least one side and another angle or side).
Many do not know that the standard calculator that is part of every Windows installation also has more robust versions: Standard, Scientific, Programmer, and Statistics. All of these are instantly available from the View menu. Standard is a fairly standard four banger. Scientific has things like trig functions, powers, roots, factorials, hyperbolic functions, angles in several units, etc. The Programmer version allows you to calculate in several different number systems; binary, octal, decimal, and hexadecimal. It also has logic functions. Finally the Statistics version has a basic set of statistical functions. All this is already on any Windows desktop with no need to download anything or go to any web page. But you do need to have paid attention in HS trig class to use the trig functions properly. And an understanding of the statistics and other ideas to use the other functions properly.
There are also some very useful additions that can be added to any of the above versions: Unit Conversions, Date Calculations, and some worksheets like Mortgage, Vehicle Lease, and Mileage. All this for free in Windows.
I keep mine on the Scientific version and I use it all the time. My laptop has a dedicated key to call it up. I suspect many others have this also. No menus or clicks, just a fast finger.

Make it fit.
You can't win and there is a penalty for trying!
