By using the formula here are the answers:

Top row: A - 117mm B - 103mm C - 233mm

Bottom row: A - 202mm B - 57mm C - 232mm

here is the work

Top row A: 10^2 + 6^2 = x^2  136 =x^2, or sqrt136 cm = 11.66 cm=116.6 mm=117 mm by rounding

Top row B: 9^2+5^2 = x^2 106=x^2 or sqrt106=x = 10.3cm = 103mm

Top row C: 20^2+12^2=x^2 = 544=x^2=sqrt544 = x = 23.3cm=x = 233mm

Bottom row A: 23^2=11^2+x^2 = 529=121+x^2 = x^2=408 = sqrt408=x = 20.2cm = 202mm

Bottom row B: 9^2=7^2+x^2 = 81 = 49+x^2 = x^2=32 = sqrt32=x = 5.7cm = 57mm

Bottom row C: 30^2=19^2+x^2 = 900=361+x^2 = 539=x^2 = sqrt539 = x = 23.2 cm or 232mm

Hope this helps :)

can you show the work?

All  of  these  are  exactly  the  same

hypotenuse  =sqrt   [  leg 1^2   +  leg2^2  ]

I'll do the first one....you  should  be  able  to  do  the rest

6cm  =  60mm       10cm  =  100 mm

hypotenuse  =sqrt  (60^2  + 100^2)   =  sqrt  13600  ≈   117  mm   May 25, 2021
