Question

Find the missing side

Answer 1

I would say 52 because of the other side of the shape that is similar to the missing side is 48 . So if the missing side is just a bit longer than the other side it is 52

Answer 2

${a}^{2} + {b}^{2} = {c}^{2}$

${20}^{2} + {48}^{2} = {2704 }^{2}$

$\sqrt{2704} = 52$

The missing side is 52 cm.
