How do I calculate the missing dimensions? (Geometry)

[Freddysandin]

Hi,

I am planning to order these records but I am missing some measurements. Tried to figure it out myself but apparently, I'm lacking intelligence.
Help wanted 🙂

- How do I find the markings X?

I'm having a bit of trouble seeing your numbers, but what I get is:

XA = 1455 + 142 - 160 = 1437 mm
XB = 1420 +142 - 160 = 1402 mm
XC = 890 - 160 = 730 mm
XD = 2475 - 160 = 2315 mm

Check that I've read the numbers correctly!

The beveled ends of the countertops will be isosceles triangles with sides of equal lengths, see for example https://naturvetenskap.se/matematik/geometri/tva-speciella-trianglar/#google_vignette

The beveled ends of the countertops become isosceles triangles with equal legs, see for example [link]

Thanks a lot!
