Question

Find the length of the missing side​

Answer 1

x is 5 cm

Explanation:

From pythogras theorem:

`{a}^(2) + {b}^(2) = {c}^(2)`

a is x cm

b is 12 cm

c is 13 cm

`{x}^(2) + {12}^(2) = {13}^(2) \\ {x}^(2) = {13}^(2) - {12}^(2) \\ {x} = \sqrt{ {13}^(2) - {12}^(2) } \\ x = √(169 - 144) \\ x = √(25) \\ x = 5 \: cm`
